What Is Intercrural Sex? The Overlooked Intimacy Option

Every once in a while, I come across a term that perfectly names something people have been doing forever without a word for it. Intercrural sex is one of those terms. Chances are you've done it, considered it, or will at some point - you just might not have known what to call it.

So What Is It?

Intercrural sex (also called interfemoral sex, femoral sex, or simply "thigh sex") is sexual activity where one partner thrusts between the other partner's thighs. There's no penetration of the vagina or anus - the friction and sensation come from the thighs pressed together around the penis or a toy.

The word comes from Latin: "inter" (between) and "crura" (legs). Literally, sex between the legs.

It's one of the oldest forms of sexual activity - historical records from ancient Greece and other cultures reference it regularly. For various practical and cultural reasons, it's been a go-to option for centuries.

Why People Choose Intercrural Sex

There are lots of reasons someone might opt for thigh sex over penetrative options:

Virginity Preservation

For people who want to avoid penetrative sex - whether for personal, religious, or other reasons - intercrural offers intimacy and mutual pleasure without crossing that line. This has historically been one of its most common uses.

Pregnancy Prevention

No penetration means no pregnancy risk (as long as ejaculation happens away from the vaginal area). It's not foolproof as a birth control method - sperm can travel if things get messy - but it's lower risk than penetrative sex.

STI Risk Reduction

Without exchange of fluids into body cavities, the risk of transmitting most STIs is significantly reduced. Not eliminated - skin-to-skin contact can still transmit some infections - but reduced.

When Penetration Doesn't Work

Penetrative sex isn't always possible or comfortable. Pain conditions, anatomy differences, erectile issues, vaginismus, recent surgery, pregnancy - there are many situations where intercrural offers an alternative.

Variety

Sometimes you just want something different. Intercrural is a distinct sensation from other sexual activities and adds variety to an intimate repertoire.

Foreplay or Warm-Up

Some couples use intercrural as part of foreplay, building arousal before moving to penetration. The external stimulation and closeness work as a prelude.

How to Do It

The basic mechanics are straightforward, but here are positions that work well:

Spooning Position

Both partners lie on their sides, one behind the other (like spooning). The partner in back thrusts between the other's thighs from behind. This is comfortable, sustainable, and allows for plenty of other touching and closeness.

Face-to-Face Lying Down

Partners face each other lying down, legs intertwined. One partner's thighs create the space for thrusting. This allows for kissing, eye contact, and upper body contact.

From Behind (Standing or Kneeling)

One partner bends over or kneels while the other enters from behind, thrusting between closed thighs rather than penetrating. This mirrors doggy-style positioning but without penetration.

Missionary Variation

One partner lies on their back with legs together. The other partner straddles their thighs and thrusts in the space where the thighs meet. This can simulate penetrative positions while being external.

Tips for Maximum Pleasure

Lubrication Is Key

Unlike penetrative sex where natural lubrication or vaginal moisture is present, thigh sex happens on skin that's naturally drier. Generous use of lube makes the experience much smoother and more pleasurable. Water-based lube works well and is easy to clean up.

Pressure Matters

The receiving partner should press their thighs together with enough pressure to create friction without being uncomfortable. Experiment with how tight to squeeze - different levels of pressure create different sensations.

Positioning for Clitoral Stimulation

For people with vulvas, the positioning can be adjusted so that the shaft rubs against the clitoris during thrusting. This adds stimulation for the receiving partner that pure thigh contact doesn't provide.

Communicate About Angle

Small adjustments to the angle of thrusting can make a big difference. What feels good varies between bodies - talk about what's working.

Take Your Time

Intercrural can be extended foreplay or the main event. Either way, rushing doesn't serve it well. The sensation builds over time.

Benefits Beyond Practicality

While people often turn to intercrural for practical reasons (avoiding pregnancy or STIs), it has its own pleasures:

It feels different. The sensation isn't the same as penetration for either partner. That different-ness can be exciting on its own.

Full body contact. Many intercrural positions involve bodies pressed fully together - chest to back, skin everywhere. This can feel more enveloping than positions where you're more separated.

Less pressure. Without the goal of "successful" penetration, some people find intercrural more relaxed. There's no performance anxiety about erection quality or achieving orgasm in a particular way.

Equalizing. In heterosexual contexts, intercrural can shift the usual dynamic. The receiving partner's thighs are active - they control the pressure and can move to enhance sensation for both people.

Who Is Intercrural Sex For?

Honestly? Anyone curious about it. But it's particularly worth considering if:

• You're in a new relationship and not ready for penetrative sex
• You want to reduce STI or pregnancy risk without eliminating sexual contact
• Penetrative sex is temporarily or permanently not an option for you
• You're looking to add variety to your sexual repertoire
• You want intimate contact that's less goal-oriented than penetration often becomes
• You're in a same-sex relationship and looking for different options (it works for all genders and configurations)

Common Questions

Can you get pregnant from intercrural sex?

Pregnancy requires sperm reaching the vagina. If ejaculation happens away from the vulva, pregnancy is essentially impossible. However, if ejaculation happens on or near the vulva, sperm can potentially travel. Be mindful of where things end up.

Can you get STIs from intercrural sex?

Some STIs (like herpes or HPV) can be transmitted through skin-to-skin contact. Others (like HIV) require fluid exchange and are much less likely to transmit through intercrural sex. It's lower risk than penetrative sex but not zero risk. If either partner has visible sores or lesions, be cautious.

Does it feel as good as penetration?

It feels different, not better or worse. Some people prefer it in certain moods or situations. Others see it as a complement to penetration rather than a replacement. The answer varies by person.

Is this only for heterosexual couples?

Absolutely not. Intercrural works for any body configuration. Same-sex couples use it regularly. The mechanics work with any combination of genitals.

What This Comes Down To

Sexual options exist on a spectrum wider than most people realize. Intercrural sex occupies a useful space - more intimate than some forms of outercourse, less invasive than penetration, pleasurable in its own right.

Whether you're trying it to avoid certain risks, because penetration isn't working for you right now, or simply because you're curious - it's a legitimate form of intimacy with a long history and plenty of fans.

Don't think of it as "not real sex" or a lesser option. It's just a different option. Sometimes different is exactly what you need.
