What’s the “knee thing” on TikTok?

The knee thing is a foreplay technique where you use your knee to sexually stimulate your partner while the two of you make out. It’s typically used to stimulate the woman’s clitoris, but it can be used to stimulate any gender. To do it, insert your knee between your partner’s and gently rub it in their pleasure spot.

   The knee thing is a way to stimulate your partner with your knee. This viral TikTok sex technique involves angling your knee between your partner’s legs and gently moving it to apply pressure to their genitals while you make out with them. Although it’s typically used to stimulate the woman’s clitoris by positioning your knee at their vulva, the knee thing can be used to stimulate anyone’s genitalia, male and female alike.

How to Do the Knee Thing

1. 
   1
   Lie on a comfortable surface and start making out. Where you make out doesn’t really matter, as long as you’re somewhere where you can spread your legs and remain comfortable. A bed, couch, air mattress, or love seat all work just fine. Once you find the ideal spot, get comfortable and start making out.

   • Don’t immediately go for the knee thing once you two start making out. Take it slow and let the tension build.
   • You can lie on your side or have one person get on top of the other, whatever you’re most comfortable with!

   Place your knee between your partner's legs. If you’re on top, gently work your knee in between your partner’s legs below you, but don’t start rubbing yet. Angle your knee at their pleasure spot as you continue to make out. If you’re on your side, gently press your knee against your partner’s legs. If they open them, angle your knee towards their pleasure spot.

   • If they express that they don’t want your knee in their crotch, whether it be through body language or words, pull your knee back and cease your attempts.

   Gently use your knee to stimulate their pleasure zone. Once your partner gives you the okay (and you’ve got your knee angled correctly), start lightly rubbing your knee against their pleasure spot to get them going. Start with a slow tempo and pressure, then speed things up (or slow them down) based on you and your partner’s personal preferences.

   • To spice things up, you can use lube if you’ve opted to take your clothes off.

Does the knee thing feel good?

1. 
   If the knee is positioned correctly, it can be very pleasurable! Make sure your partner knows where to put their knee by gently nudging them in the right direction while you make out. For example, if they’re digging their knee into your thigh fold, use your legs to direct them to your pleasure spot. If they still don’t get the hint, don’t be afraid to communicate in a more direct manner.

   • For example, say “move your knee up” or “keep it gentle” if they aren’t doing it to your liking.

Other Ways to Spice Up Your Sex Life

   Bring toys into the bedroom. Dating coach & matchmaker Laura Bilotta suggests trying out some new sex toys if you’re looking to bring some spice into the bedroom. Approach your partner about the topic and gauge what they’re comfortable with. Start with small toys that encourage pleasurable exploration, like vibrators.

   Check in with your partner’s emotions. According to love & relationship coach Nicole Moore, “passionate sex usually happens when we have positive feelings toward our partner.” Happy and excited feelings typically translate into amazing sex in the bedroom. So, look at what’s going on emotionally between you and your partner to help speed up the spice.

   • See if you have any resentment or lingering feelings towards your partner (and vice versa). If so, confront them and work through them, as they will likely leak into the bedroom otherwise.
   • According to Moore, “having an honest conversation about what the two of you are feeling can be a fast track to unlocking the intimacy and passion you once felt.”

   Switch locations every now and then. Sometimes, the same creaky bed can get boring, but changing the place up can help bring that spark right back. Grab a hotel room, plan a weekend getaway, vacation, or staycation, and get busy wherever you’re at. There are also other, more taboo places you can get intimate at; all you have to do is take it outside of the bedroom. You don’t necessarily need to get a hotel room to do so.
4.

   Try new positions. Bring a new position into the bedroom to help boost the excitement between you and your partner. Sex can get routine sometimes, but trying something as little as putting a pillow under your waist or having one partner stand can help liven up the bedroom. For example, if one partner tends to stay on top, have them lie on their stomach to switch things up.

   Focus more on foreplay. According to dating coach JT Tran, “the sexual tension is more important than just the sexual release.” Dedicate time to foreplay to make sure both partners enjoy the experience and are eager to get back into bed with one another. Take things slow, let the tension build up, and really dedicate time to kissing and feeling your partner.

Is foreplay important?

Download Article

1. 
   Foreplay is very important, as it helps stimulate arousal before sex. Foreplay encompasses everything that comes before sex, including caressing, kissing, massaging, sucking, and other forms of stimulation (like the knee thing). Not only does it add an extra flair to sex, but it also helps make things more enjoyable, gives more time for vaginal lubrication, and encourages easier orgasm for both parties.
