Coital Alignment Technique (CAT): How to Do It + 3 Variations

The coital alignment technique (CAT) is a small tweak to missionary that changes a lot. Instead of thrusting in and out, the partner on top shifts their body slightly higher. Both partners then rock together, so the base of the penis and the pubic bone press and glide against the clitoris throughout vaginal sex. It's made for anyone who wants more clitoral contact during penetration without changing positions.

Many people with a vulva don't reach orgasm from penetration alone, and that's completely normal. The clitoris usually needs direct, steady stimulation, and classic missionary often misses it. CAT was described by psychotherapist Edward Eichel in the late 1980s. It's sometimes nicknamed "riding high". It aims to bring that stimulation into intercourse itself through alignment and rhythm, not force or speed.

How CAT Works

CAT has three ingredients:

• Shallow penetration. The penis (or a strap-on) stays mostly inside, and only a little of the shaft moves.
• A higher position for the top partner. Their pelvis sits a bit lower and their chest a bit higher than in regular missionary. That way their pubic bone and the base of the shaft rest against the clitoris.
• Rocking instead of thrusting. Both partners move in a slow, shared up-and-down rhythm along the length of their bodies. This keeps the pressure constant.

Because you're face to face and moving together, CAT also feels very connected. You can kiss, talk, and notice each other's reactions without breaking rhythm.

How to Do the Coital Alignment Technique Step by Step

1. Start in missionary. The receiving partner lies on their back with legs slightly apart and knees relaxed or gently bent. The top partner lies over them, chest to chest, supporting some weight on their forearms. Use plenty of lubricant, plus a condom if you use one.
2. Enter, then shift up. After penetration, the top partner slides their whole body forward, toward their partner's head, by a few centimeters (roughly an inch or two). Their pelvis drops slightly so the base of the shaft and their pubic bone settle against the clitoris.
3. Get closer. The top partner can rest more of their weight on their partner, if that feels good to both of you, and keep their legs straight or close to their partner's. The receiving partner can rest their legs straight or wrap them loosely around the top partner's calves.
4. Rock, don't thrust. The top partner presses gently forward and up. The receiving partner then tilts their pelvis upward to meet them. The movement is small and steady, like a slow wave, and contact with the clitoris never breaks.
5. Keep the rhythm. Consistency matters more than speed. If the person with the clitoris is getting close, keep doing exactly what's working rather than speeding up.

It often takes a few tries to find the right alignment, especially if your heights or body shapes differ a lot. If the penis slips out, just shift a little lower and try again.

3 CAT Variations

1. Legs Together

The receiving partner keeps their thighs close together, and the top partner places their knees outside. This narrows the angle and often makes the pressure on the vulva more concentrated. It also keeps penetration shallow, which some people prefer.

2. Pillow Under the Hips

A firm pillow or wedge under the receiving partner's lower back tilts the pelvis upward. This makes it easier to keep contact without the top partner having to slide as far. It's also handy when partners have very different heights.

3. CAT From On Top

Swap roles: the partner with the vulva lies along their partner's body instead of sitting upright. They grind their clitoris against the partner's pubic bone in the same slow rocking motion. The person on top controls the pressure and pace completely, and no one has to hold up their body weight on their arms.

Making CAT More Comfortable

• Share the weight. If the top partner's wrists, elbows, or shoulders get tired, lower onto the forearms or rest more on the partner below (ask first).
• Add a hand or a toy. A small vibrator or fingers between your bodies can boost clitoral stimulation. That isn't failing at CAT; it's using what works.
• Strap-on users: CAT works with a harness and dildo too. A harness with a firm base or a built-in vibrator adds pressure for both partners.
• Warm up first. More arousal before penetration makes the clitoris more sensitive and the whole thing easier.

When CAT Isn't the Right Fit

• Pregnancy: pressure on the belly and lying flat on the back for long periods are often uncomfortable or not recommended later in pregnancy. Try the on-top variation or side-lying positions instead, and follow the advice of your doctor or midwife.
• Back, neck, or shoulder problems: holding the body up and pushing forward can strain the top partner. Switch to the on-top variation or support yourselves with pillows.
• Pain during sex: if penetration hurts, stop. Recurring pain deserves a conversation with a healthcare provider, not pushing through it.
• Breathing comfort: if the weight on top feels like too much, it is too much. Say so, and shift or swap.

CAT changes position, not risk. Condoms or other barriers still matter for STI and pregnancy prevention.

Communication and Consent

CAT works best when you're talking. Small adjustments ("a bit higher", "slower", "just like that") make a big difference, and only the person feeling it knows what's working. Agree beforehand that either of you can pause, change the pace, or stop at any time, and that trying it is no promise to finish a certain way. If it doesn't click the first time, it's not a problem. It's just two people learning each other.
