Double penetration (DP) is a fantasy many couples want to explore, but it can feel intimidating without the right gear and know-how. A double penetration strap-on lets you or your partner experience simultaneous vaginal and anal stimulation — or double vaginal — using a single harness and a dual-ended toy. With a little preparation and communication, it can be a deeply pleasurable addition to your play.

This guide walks you through everything from choosing the right harness and toy to getting into position and moving together comfortably. Whether you're brand new to strap-ons or have used one before, these tips will help you make the most of your double penetration experience.

What Is a Double Penetration Strap-On?

A double penetration strap-on consists of a harness worn by one partner (the wearer) and a double-ended dildo or vibrating rabbit-style toy that inserts into both partners at once. Unlike a standard strap-on, where the wearer only receives the base of the toy, a DP strap-on is designed so that the wearer also gets internal stimulation from the shorter end while the longer end penetrates their partner.

Some popular options include the Lovehoney Universal Strap-On Harness, which fits most bullet or double-ended toys, and vibrating models like the ROMP Join Rechargeable Couple's Vibrator, which offers dual motors for shared sensation. For wearers who want clitoral or G-spot stimulation, a vibrating double dildo strap-on can add an extra layer of pleasure.

  • Choose a harness with adjustable straps for a secure, comfortable fit.
  • Look for double-ended toys made of body-safe silicone for easy cleaning and comfort.

Step 1: Choose the Right Harness and Toy

Start with a harness that fits the wearer snugly without digging in. The Lovehoney Universal Strap-On Harness is a great beginner-friendly option because it comes with interchangeable rings to fit different toy sizes and is fully adjustable. For a smoother experience, pair it with a double-ended dildo that has a gentle curve and a flared base for safety.

If you want vibration, consider the We-Vibe X Lovehoney Jive Lite App-Controlled Love Egg Vibrator — while it's not a double-ended toy, it can be used inside the wearer during DP with a compatible harness. Alternatively, a dedicated vibrating rabbit strap-on like the ROMP Join gives both partners simultaneous buzz. Make sure the toy is long enough to reach both partners comfortably — typically 7 to 10 inches total length.

  • Measure the distance between both partners' bodies to estimate the toy length you need.
  • Test the toy's flexibility: a semi-rigid silicone holds its shape better during thrusting.

Step 2: Prepare Your Body and Mind

Communication is key. Talk about who will wear the harness, what positions you want to try, and what feels good for each of you. Use plenty of water-based lubricant on both ends of the toy — silicone lube can damage silicone toys, so stick with a high-quality water-based option. Warm up with fingers or a smaller toy before attempting DP, especially if anal penetration is involved.

The wearer should also practice inserting their end of the toy while lying down or standing to find the most comfortable angle. If you're using a vibrating toy like the ROMP Join, test the vibration settings beforehand so you know which intensity works best for both of you.

  • Apply lube to the harness straps where they touch skin to reduce friction.
  • Set aside at least 30 minutes of uninterrupted time for your first session.

Step 3: Put on the Harness and Insert the Toy

Have the wearer put on the harness and adjust the straps so it sits snugly against their pubic bone. Slide the double-ended dildo through the O-ring so the shorter end faces the wearer and the longer end points outward. The wearer then inserts their end slowly, using lube and taking their time. The toy should feel secure and not slip out during movement.

If you're using a vibrating double dildo strap-on, make sure the battery compartment or charging port is accessible and that the controls are easy to reach. Once the wearer is comfortable, the receiving partner can guide the other end into their vagina or anus. Start with shallow thrusts and let your partner control the depth and rhythm.

  • Have the receiving partner lie on their back with knees bent for easier insertion.
  • Use a towel underneath to catch excess lube and make cleanup easier.

Step 4: Find a Comfortable Position

The classic position for DP strap-on play is the receiving partner on their back with legs open, while the wearer kneels or stands between their legs. This gives the wearer good control and allows both partners to see each other. Another option is spooning: both partners lie on their sides, with the wearer behind the receiver. This position is great for slow, intimate thrusting.

For deeper penetration, the receiving partner can get on all fours while the wearer kneels behind them. The wearer can lean forward to adjust the angle. If you're using the Lovehoney Universal Strap-On Harness, the adjustable straps make it easy to shift positions without the harness slipping.

  • Place a pillow under the receiving partner's hips to change the angle of entry.
  • Switch positions every 5-10 minutes to avoid numbness or discomfort.

Step 5: Move Together and Communicate

Start with slow, rhythmic thrusts and pay attention to your partner's breathing and body language. The wearer should focus on rocking their hips rather than just pushing forward — this creates a more natural motion and keeps the toy in place. Both partners can use their hands to stimulate their own clitoris or testicles for added pleasure.

Check in verbally every few minutes: ask if the depth feels good, if the angle needs adjusting, or if you need more lube. If you're using a vibrating toy like the We-Vibe Jive Lite, you can change the pattern mid-session to keep things fresh. Don't rush — the goal is mutual enjoyment, not a race to orgasm.

  • Use a code word like 'pause' or 'yellow' to signal discomfort without breaking the mood.
  • Keep a small bottle of lube nearby for reapplication.

Cleaning and Aftercare Tips

After play, remove the toy from the harness and wash both ends with warm water and a toy cleaner or mild soap. Silicone toys can be boiled for 3 minutes to sanitize, but check the manufacturer's instructions first. Let the toy air dry completely before storing it in a dust-free bag or container.

Aftercare is just as important. Cuddle, talk about what you enjoyed, and check in with each other's emotional state. If any partner feels sore, apply a cooling gel or take a warm bath. With good communication and the right gear, double penetration can become a regular, exciting part of your shared sex life.

  • Store silicone toys separately from silicone-based lubricant to avoid chemical reactions.
  • Replace the harness if the O-ring or straps show signs of wear.

Using a double penetration strap-on is all about preparation, patience, and partnership. By choosing a comfortable harness like the Lovehoney Universal Strap-On Harness, a body-safe double-ended toy, and following these steps, you and your partner can explore DP with confidence and pleasure. Remember: lube generously, communicate openly, and enjoy the journey together.
