How to Prepare for a Threesome

Discuss Boundaries with Your Partner(s)

Before inviting or agreeing to a third person, all participants must discuss:

• What activities are okay? Kissing, oral sex, penetration, anal sex, toy use?
• Who can do what with whom? Can both partners touch the third? Can the third touch both partners equally?
• Off-limit acts: Are there specific activities, positions, or body parts that are off-limits?
• Emotional boundaries: Is this a one-time experience or potentially ongoing? Can you develop feelings for the third?

Example conversation starters:

• "I'm comfortable with oral sex and touching, but I'd prefer penetration stays between us."
• "I'd like us both to give equal attention to the third person."

Choose the Right Third Person

Ideal qualities:

• Clear communication: They understand and respect boundaries.
• No emotional entanglement: Unless you're pursuing polyamory, avoid choosing a close friend or someone with romantic feelings for either partner.
• Shared expectations: They want the same type of experience (casual, exploratory, ongoing).

Where to find a third:

• Dating apps: Feeld, OkCupid, and 3Fun are designed for non-monogamous connections.
• Swinger clubs or events: Environments where group sex is normalized and expected.
• Mutual friends (with caution): Only if all parties are mature, communicative, and comfortable.

Warning: Avoid pressuring friends or acquaintancescoercion violates consent.

Establish a Safeword or Check-In System

A safeword allows anyone to pause or stop the encounter immediately.

Examples:

• Traffic light system: "Green" = continue, "Yellow" = slow down/check in, "Red" = stop immediately.
• Verbal check-ins: "Is everyone still feeling good?" or "Should we keep going?"

According to Planned Parenthood's guide to consent, ongoing, enthusiastic consent is essential in all sexual encountersespecially group sex.

Step-by-Step: How to Have a Successful Threesome

Step 1: Set the Scene

• Choose a comfortable location: A neutral space (hotel) can reduce emotional attachment; your home offers familiarity but may create jealousy.
• Prepare the space: Clean sheets, plenty of lube, condoms, towels, and water nearby.
• Create ambiance: Dim lighting, music, and comfortable temperature.

Step 2: Start with Non-Sexual Touch

• Ease into it: Begin with kissing, massage, or cuddling to build comfort and arousal.
• Equal attention: Ensure no one feels left outrotate who's receiving and giving attention.
• Check in verbally: "Does this feel good?" "Are you comfortable?"

Step 3: Explore Together

Popular threesome activities:

• Oral sex chains: One person receives oral while giving it to another.
• Double oral: Two people perform oral sex on one person simultaneously.
• Penetration + oral: One partner penetrates while the third performs oral on them or the receiving partner.
• Toy use: Incorporate vibrators or bullet vibrators for added stimulation.

Tip: Use sex toys for couples to enhance stimulation and ensure everyone stays engaged.

Step 4: Prioritize Communication Throughout

• Ask permission before trying new things: "Can I try this?" or "Is it okay if I..."
• Give positive feedback: "That feels amazing," "I love this."
• Check in if someone seems quiet or distant: "Are you okay?" "What do you need?"

Step 5: Aftercare

Aftercare is essential for emotional wellbeing after intense sexual experiences.

What to do:

• Cuddle or hold each other: Physical closeness helps transition out of the heightened state.
• Hydrate and rest: Offer water, snacks, and a moment to recover.
• Debrief: Talk about what everyone enjoyed, what worked, and what to adjust next time.
• Check in the next day: Text the third person and your partner(s) to ensure everyone still feels good about the experience.

Common Challenges & How to Handle Them

Jealousy

Why it happens: Seeing your partner with someone else can trigger unexpected emotions.

How to manage:

• Pause and communicate: Use your safeword or verbally express discomfort.
• Focus on connection: Make eye contact with your partner, hold hands, or check in verbally.
• Debrief afterward: Discuss feelings without blamejealousy is natural and doesn't mean the experience was wrong.

One Person Feeling Left Out

Why it happens: Unequal attention distribution or one person naturally connecting more with another.

How to prevent:

• Rotate positions frequently: Ensure everyone gives and receives attention.
• Assign roles: Take turns being the "focus" person who receives attention from both others.
• Use toys: Vibrators keep someone stimulated even when hands and mouths are busy elsewhere.

Awkward Logistics

Why it happens: Coordinating three bodies, especially in small spaces, can be clumsy.

How to manage:

• Use larger surfaces: King beds, floors with cushions, or spacious hotel rooms.
• Communicate positions: "Let's try this," "Can you move here?"
• Laugh it off: Awkwardness is normal humor reduces tension.

Safety & Protection in Threesomes

Sexual Health

• Use barrier protection: Condoms for penetration, dental dams for oral-vulva contact.
• Change condoms between partners: Prevents cross-contamination of STIs.
• Get tested regularly: All participants should have recent STI test results.

According to Mayo Clinic guidance on safe sex, consistent barrier use and regular testing are essential for reducing STI transmission in multi-partner encounters.

Emotional Safety

• Respect boundaries: If someone says no or uses a safeword, stop immediately.
• Avoid coercion: Everyone must freely consent without pressure.
• Check in afterward: Ensure all participants feel respected and cared for.

Threesome Etiquette

For Couples Inviting a Third

• Treat the third as a person, not a toy: Check in on their comfort and pleasure.
• Avoid excessive PDA with your partner: The third should feel included, not like a voyeur.
• Communicate logistics clearly: Duration, boundaries, and expectations.

For the Third Person ("Unicorn")

• Respect the couple's boundaries: Don't push limits or try to create a wedge.
• Communicate your needs: You deserve pleasure and respect too.
• Exit gracefully: If the dynamic isn't working, it's okay to stop.
