CAT stands for Coital Alignment Technique, a sexual position and rhythmic method used during penis-in-vagina intercourse. It is a modification of the missionary position designed to maximize clitoral stimulation through sustained, grinding contact rather than the in-and-out thrusting typical of standard missionary sex. In the CAT, the penetrating partner shifts their body upward so that the base of their penis and pubic bone press directly against the clitoris. Both partners then move together in a coordinated rocking or grinding rhythm, with the receiving partner using upward strokes and the penetrating partner using downward counter-strokes. The goal is continuous friction and pressure on the clitoris throughout the act, which many people with vulvas find significantly more likely to lead to orgasm than conventional thrusting. CAT is considered a technique for mutual pleasure rather than a fetish or power-based dynamic. It requires coordination and communication between partners but does not require props, toys, or special equipment. It is accessible to most bodies and is often recommended by sex educators as a practical method for closing the orgasm gap in heterosexual partnered sex.
In practice, CAT begins in a missionary-style setup, but the penetrating partner then slides their body a few inches upward so their pelvis is riding higher than usual. This shift means the base of the penis rests against the clitoral area rather than the entry point being the focus. From there, both partners adopt a rocking or wave-like motion: the receiving partner tilts their pelvis upward, and the penetrating partner presses downward, creating a rhythmic back-and-forth that keeps the clitoris engaged with almost continuous friction and pressure.
The pace tends to be slower and more deliberate than typical thrusting, which many people describe as feeling more intimate and connected. Some couples use a pillow under the receiving partner's hips to adjust the angle. Others incorporate slight side-to-side grinding within the same framework.
What draws people to CAT is largely practical: studies and surveys consistently show that most people with vulvas do not orgasm from penetration alone, and CAT directly addresses that by building clitoral contact into the core mechanics of intercourse. It requires genuine cooperation and attunement between partners, which many find enhances emotional connection alongside physical pleasure. It is also appealing because no additional toys or accessories are needed, though a vibrator can be added for extra stimulation if both partners are comfortable with that.
CAT is a low-risk technique, but a few considerations apply. Partners should communicate openly about pressure and rhythm, since the grinding motion can feel too intense on the clitoris for some people and not intense enough for others. Adjust body positioning gradually and check in verbally. People with pelvic pain conditions, hip injuries, or lower-back sensitivity should move slowly and stop if discomfort arises. Because CAT involves sustained close-body contact, standard safer-sex practices (condoms, regular STI testing) remain relevant. Emotional comfort with the face-to-face intimacy of the position is also worth discussing beforehand.
In regular missionary, the penetrating partner's hips are aligned with the receiving partner's hips and the main motion is in-and-out thrusting. In CAT, the penetrating partner shifts upward so the pubic bone and base of the penis create direct, sustained friction against the clitoris. The movement is a coordinated rocking grind rather than thrusting.
The classic CAT description involves a penis, but the core principle, sustained pubic-bone-to-clitoris grinding pressure in a missionary-style position, can be adapted for couples using a strap-on or harness. The positional logic and rhythmic coordination apply the same way.
Yes, because the penetrating partner's body shifts upward, the depth of penetration is typically shallower than in standard missionary. For some people this is a benefit, especially if deep penetration causes discomfort. For others who enjoy depth, CAT can be combined with toys or alternated with other positions.
Most couples find that CAT takes at least a few sessions to feel natural, since it requires coordinating a new rhythm together. Communicating during the act, going slowly at first, and being willing to pause and reposition are all normal parts of the learning curve.
The technique was first described in peer-reviewed sexology literature in the 1980s by Edward Eichel and colleagues, and some published studies reported higher rates of orgasm for the receiving partner compared to standard missionary. The research base is limited in size, but the technique is widely cited by sex educators as a practical approach to increasing clitoral engagement during partnered sex.
Yes. A small external vibrator placed between the partners or held by one partner can complement the grinding motion without disrupting the technique. Some people find the combined stimulation more reliable for orgasm. Communication about what feels good in the moment is key when adding a toy to any position.
