The speed bump—also called the prone bone or flat doggy—offers a unique angle for penetration that many couples find intensely satisfying. This position combines the deep access of rear-entry with the intimacy of full-body contact.
Whether you're looking to target specific pleasure zones or simply want to expand your repertoire, this guide covers everything from basic technique to advanced variations.
What Is the Speed Bump Sex Position?
The speed bump involves the receiving partner lying flat on their stomach while the penetrating partner lies on top, entering from behind. Unlike traditional doggy style where the receiver is on hands and knees, this flattened variation changes the angle dramatically.
Why It's Called Speed Bump
The name comes from the receiving partner's raised hips creating a "bump" that the penetrating partner moves over—similar to driving over a speed bump. Some also call it the "prone bone" because of the face-down (prone) positioning.
Key Characteristics
- Receiving partner: Face down, legs together or slightly apart, pelvis tilted
- Penetrating partner: On top, legs straddling or alongside receiver's legs
- Penetration angle: Shallow to moderate depth, targets anterior (front) vaginal wall
- Body contact: Maximum skin-to-skin connection throughout
- Control: Primarily with penetrating partner, though receiver can adjust hip angle
Understanding human sexual behavior through different positions helps normalize exploration and variety.
Why People Love the Speed Bump Position

This position offers specific advantages that make it a favorite for many couples.
Physical Benefits
G-Spot Stimulation: The downward angle naturally targets the G-spot (located on the anterior vaginal wall about 2-3 inches inside). Many receivers find this angle hits the right spot without manual adjustment.
Tight Sensation: Legs together creates a tighter fit that intensifies sensation for both partners. The penetrating partner feels increased friction, while the receiver experiences fuller sensation.
Deep Yet Controlled Penetration: While the angle allows depth, the positioning naturally prevents overly aggressive thrusting that can cause discomfort with sensitive cervixes.
Reduced Physical Strain: Unlike positions requiring significant core strength or flexibility, speed bump works for various fitness levels and body types.
Psychological Appeal
Intimacy Through Contact: Full-body connection creates closeness that some rear-entry positions lack. The penetrating partner can whisper, kiss neck and shoulders, and maintain constant touch.
Vulnerability and Trust: The receiving partner's face-down, accessible position creates a sense of surrender that appeals to some people's desires for submissive experiences.
Dominant Dynamics: For penetrating partners interested in power exchange, the position naturally emphasizes their control and the receiver's receptiveness.
Lazy Sex Option: When both partners want connection without athletic performance, speed bump provides pleasure with minimal effort required.
For couples exploring intimacy together, browse sex toys for couples that complement various positions and dynamics.
Step-by-Step: How to Do the Speed Bump Position
Proper setup and communication ensure comfort and maximum pleasure for both partners.
Initial Positioning
- Receiving partner lies face down: Start on a comfortable surface (bed works best) lying completely flat on stomach
- Arms placement: Above head, at sides, or under pillow—whatever feels comfortable
- Leg position: Begin with legs together, toes pointed or feet flexed naturally
- Hip elevation (optional): Place a pillow or wedge under hips to adjust angle
- Head position: Turn to one side for comfortable breathing
Penetrating Partner Setup
- Straddle or kneel: Position yourself over receiver's hips and thighs
- Leg placement options:
- Legs outside: Kneel with your knees on either side of receiver's hips
- Legs inside: Place your legs between receiver's slightly parted thighs
- One leg inside, one out: Asymmetric but offers different angle
- Support your weight: Use hands placed beside receiver's shoulders to avoid crushing them
- Align properly: Position for entry may require receiver to tilt pelvis slightly upward
Entry and Movement
- Start with external stimulation: Tease with gentle touches before penetration
- Use adequate lubrication: This angle benefits greatly from additional lubrication—apply generously
- Enter slowly: The tight fit and angle require gradual, careful initial penetration
- Find comfortable depth: Not every position works for maximum depth—find what feels good
- Establish rhythm: Shallow, grinding motions often work better than deep thrusting
- Adjust as needed: Receiver can arch back slightly or press hips down to change sensation
During Sex
- Communicate continuously: "More pressure," "slower," "adjust angle slightly left"
- Monitor comfort: Check in about breathing, hip flexor comfort, and sensation quality
- Vary technique: Alternate between grinding, shallow thrusts, and deeper movements
- Add stimulation: Penetrating partner can reach around for clitoral contact
- Maintain connection: Use voice, touch, and rhythm to stay synchronized
For additional G-spot stimulation options, explore G-spot vibrators that can be used before or during position changes.
Exiting Safely
- Slow withdrawal: Exit gradually rather than sudden pulling out
- Roll gently: Penetrating partner shifts weight to side before fully separating
- Check in immediately: "How was that for you?" "Any discomfort?"
- Provide aftercare: Cuddle, hydrate, discuss the experience

Pillow and Prop Enhancements
Pillow Under Hips: Elevates receiver's pelvis, increasing penetration angle and making G-spot targeting easier. Start with one pillow; add more for steeper angle.
Wedge Pillows: Purpose-designed sex positioning wedges provide stable, optimal angles without constant adjustment. Worth the investment for regular use.
Under Chest Support: Small pillow under receiver's chest allows easier head turning and breathing while maintaining flat lower body.
Ankle Support: Rolled towel or small pillow under ankles prevents foot cramping during longer sessions.
Penetrating Partner Modifications
Kneeling Upright: Instead of lying on top, kneel upright while holding receiver's hips. Provides more leverage and visual access but reduces body contact intimacy.
Lying Fully Flat: Penetrating partner lies completely flat on receiver's back with minimal weight support. Creates maximum contact but limits movement range.
Seated Variation: Penetrating partner sits back on heels while receiver remains flat. Changes angle significantly and allows for different rhythm.
Adding Stimulation
Manual Clitoral Contact: Penetrating partner reaches underneath to stimulate clitoris during penetration. Requires arm strength and coordination but dramatically increases receiver pleasure.
Vibrator Integration: Place a bullet vibrator between receiver's body and mattress, positioned against clitoris. Hands-free stimulation for both partners.
Anal Play (If Consensual): The position offers easy access for gentle external or internal anal stimulation. Always discuss beforehand and use appropriate lubricant.
Nipple Stimulation: Receiver can stimulate their own nipples or penetrating partner can reach around when not supporting full weight.
Who Benefits Most from Speed Bump?

Certain body types, preferences, and situations make this position particularly appealing.
Physical Considerations
Receivers Who Enjoy G-Spot Stimulation: The angle specifically targets this area, making it ideal for people who respond strongly to anterior vaginal wall pressure.
People With Lower Back Issues: Unlike doggy style which can strain the lower back, lying flat reduces spinal stress significantly.
Those Sensitive to Deep Penetration: The position naturally limits depth compared to other rear-entry angles, making it comfortable for people with sensitive cervixes.
Partners With Size Differences: Height differences that complicate other positions become less problematic when both are lying flat.
Individuals With Limited Flexibility: No splits, deep squats, or contortions required—just lying down and basic movement.
Psychological Preferences
Submissive Tendencies: The receiving partner's vulnerable, accessible position appeals to those who enjoy power exchange dynamics.
Intimacy Seekers: Full-body contact throughout creates closeness some find missing in more athletic positions.
Visual Stimulation Enjoyers: Penetrating partners get a unique view that many find highly arousing.
Lazy Day Sex Fans: When energy is low but desire is present, speed bump delivers satisfaction without exhaustion.
Common Challenges and Solutions
Even straightforward positions present obstacles. Here's how to address frequent issues.
Challenge: Difficulty With Initial Penetration
Causes: Tight angle, insufficient arousal, inadequate lubrication, anatomy mismatch.
Solutions:
- Extend foreplay significantly before attempting penetration
- Use generous amounts of water-based or silicone lubricant
- Receiver tilts hips upward by engaging core or using pillow support
- Try entering in a different position, then transitioning to speed bump
- Receiver spreads legs wider initially, then closes once penetration achieved
- Consider that some body combinations make certain positions incompatible—that's normal
For tips on safe and comfortable penetration, consult trusted sexual health resources.
Challenge: Breathing Difficulty for Receiver
Causes: Face pressed into mattress, chest compression, claustrophobic feeling.
Solutions:
- Turn head to side rather than face-down
- Use firmer mattress that doesn't create face-sink
- Place small pillow under chest to elevate upper body slightly
- Penetrating partner supports more of their own weight
- Take regular breaks to shift position and breathe deeply
- Try modified version with receiver propped on forearms
Challenge: Hip Flexor or Lower Back Discomfort
Causes: Sustained hip extension, anterior pelvic tilt, pre-existing tightness or injury.
Solutions:
- Stretch hip flexors and lower back before sex (yoga poses like cobra, child's pose)
- Use pillows under hips to reduce extension angle
- Limit session duration—switch positions before pain develops
- Strengthen core and hip muscles through regular exercise
- Consider physical therapy if pain persists outside sexual activity
- Try frog-leg variation that reduces hip extension
Challenge: Limited Movement Range for Penetrating Partner
Causes: Tight space between bodies, leg positioning restrictions, lack of leverage.
Solutions:
- Receiver spreads legs slightly to create more room
- Penetrating partner uses grinding/circular motions instead of thrusting
- Focus on quality of sensation rather than vigorous movement
- Use hands on receiver's hips for additional leverage
- Try kneeling upright variation for more movement freedom
- Accept that this position emphasizes intimacy over athleticism
Challenge: Receiver Can't Reach Orgasm
Causes: Insufficient clitoral stimulation, wrong angle, psychological barriers, positioning discomfort.
Solutions:
- Add manual or vibrator-based clitoral stimulation
- Adjust pillow height under hips to change G-spot contact angle
- Receiver practices pelvic floor contractions during penetration
- Extend foreplay and arousal before penetrating
- Use this as one position in sequence rather than sole method
- Remove pressure—make exploration about pleasure, not achievement

Enhancing the Speed Bump Experience

Once comfortable with basics, these additions create even more satisfying sessions.
Sensory Elements
Temperature Play: Ice or warm massage oil on back and buttocks creates contrasting sensations during penetration.
Texture Variation: Silk sheets, faux fur throws, or other fabrics change the tactile experience dramatically.
Scent: Aromatic candles or essential oils (applied to skin, not genitals) enhance ambiance.
Sound: Background music, guided audio, or vocal encouragement all contribute to experience quality.
Communication Techniques
Verbal Guidance: Real-time feedback like "slower," "harder," "right there, don't move" optimizes technique.
Body Language: Receiver can press back into penetrating partner to signal "more" or flatten against mattress to signal "ease up."
Sounds: Moaning, breathing changes, and vocal enthusiasm communicate without interrupting flow.
Pre-Arranged Signals: Establish meanings for specific touches (tap shoulder = need break, grab hand = perfect).
Power Exchange Elements (If Desired)
For couples interested in dominance/submission dynamics:
- Light restraints on receiver's wrists (silk ties, soft cuffs)
- Verbal commands or dirty talk emphasizing control
- Hair pulling (gentle, with clear consent and safe technique)
- Spanking or impact play during position (discuss boundaries first)
- Orgasm control (edging, denial, permission requirements)
Safety, consent, and communication remain paramount in any power exchange scenario.
Sequential Positioning
Speed bump works beautifully as part of a progression:
Warm-Up Sequence:
- Start with missionary for eye contact and intimacy
- Transition to receiver on top for their control
- Move to speed bump for G-spot focus
- Finish in favorite position for climax
Stamina Builder:
- Begin in speed bump for intense G-spot stimulation
- Switch to spooning for rest while maintaining penetration
- Return to speed bump for final intensity
- Transition to position that allows simultaneous clitoral stimulation
Safety and Health Considerations
Practicing speed bump safely ensures ongoing enjoyment without injury or complications.
Physical Safety
Cervical Sensitivity: If deep thrusts cause pain, the angle may be hitting your cervix. Adjust hip tilt, use less depth, or switch positions.
Hip Flexor Strain: Stop if sharp pain develops in front of hips or lower abdomen. Stretch and rest before resuming.
Breathing Access: Never compromise breathing for positioning—adjust immediately if respiratory distress occurs.
Neck Strain: Keeping head turned one direction too long causes stiffness. Alternate sides or face down with breathing space.
Weight Distribution: Penetrating partners must support their own weight to avoid crushing receiver's ribcage or restricting breathing.
Hygiene Practices
- Shower beforehand if concerned about cleanliness
- Use fresh, clean sheets for comfort and hygiene
- Keep lubricant and tissues within reach for easy cleanup
- Urinate after sex to reduce UTI risk (especially important for vulva-owners)
- Wash toys before and after use with appropriate cleaners
Contraception and STI Prevention
- Position doesn't affect pregnancy risk—use appropriate contraception
- Condoms can shift or break with vigorous movement—check periodically
- Regular STI testing matters regardless of position preferences
- Communicate about testing history and safer sex practices

Frequently Asked Questions
Is the speed bump position safe during pregnancy?
During early pregnancy (first trimester), speed bump is generally safe for most people. However, as pregnancy progresses, lying flat on the stomach becomes uncomfortable or impossible. After the first trimester, most healthcare providers recommend avoiding prolonged periods on your stomach. Side-lying, hands-and-knees, and receiver-on-top positions work better during later pregnancy. Always consult your healthcare provider about specific activities during pregnancy.
Can the speed bump work for anal sex?
Yes, the speed bump adapts well to anal penetration. The angle and positioning actually work quite favorably for anal access. However, additional considerations apply: use significantly more lubricant (anus doesn't self-lubricate), go even slower during initial penetration, communicate constantly about comfort, and never transition from anal to vaginal without thorough cleaning or condom change. The tight leg positioning may create more intense sensation, so proceed carefully.
What if one partner is much larger or smaller than the other?
Body size differences require minor adjustments but rarely prevent enjoying speed bump. If the penetrating partner is much larger, they must be especially careful about weight distribution—use arms to support body rather than resting full weight on receiver. If the receiver is significantly larger, additional pillows under hips help with angle alignment. Height differences matter less in this horizontal position than in standing or kneeling variations.
How do you add clitoral stimulation during speed bump?
Several options exist: the penetrating partner can reach underneath receiver's body to manually stimulate (requires arm strength and coordination), the receiver can reach between their own legs while lying flat, or place a vibrator between the receiver's body and the bed surface, positioned against the clitoris. The third option provides hands-free stimulation that doesn't require athletic coordination.
Is this position good for quickies or better for longer sessions?
Speed bump works well for both. For quickies, the position allows quick entry and intense sensation without complex setup. For longer sessions, the minimal physical strain on both partners allows extended duration without fatigue. The position's versatility makes it suitable for whatever timeframe you have available.
Can you use sex toys during the speed bump position?
Absolutely. Bullet or egg vibrators placed between the receiver's body and mattress provide clitoral stimulation. Internal toys like G-spot vibrators can be used beforehand to enhance arousal. Some couples enjoy adding anal toys for receivers interested in dual penetration. Just ensure whatever you use is body-safe and doesn't interfere with comfortable positioning.
Final Thoughts: Exploring Angles and Intimacy
The speed bump position offers a unique combination of physical sensation, psychological dynamics, and practical accessibility. Its G-spot targeting angle, tight sensation, and full-body contact create experiences many couples find intensely satisfying.
Like any position, speed bump requires communication, willingness to adjust, and understanding that what works for one couple may not work for another. Bodies are wonderfully diverse—celebrate finding what brings you and your partner pleasure rather than forcing any prescribed method.
Start slowly, prioritize comfort alongside intensity, and remember that great sex comes from connection and communication rather than perfect technique.
