You’ve probably heard of the orgasm gap: in heterosexual relationships, women statistically have fewer orgasms than men. Much can — and should! — be done to improve that, starting with a better understanding of what your partner needs to reliably get off. A good place to start is upgrading your go-to bedroom moves.

Take the missionary position, for example. You and your partner may count this classic sex position as a favorite because of the intimacy it provides, but sex therapists say one small tweak can take it from “good” to much, much better.

The “coital alignment technique,” aka CAT, is a modified version of missionary sex, where the man rides a little higher, sliding his body up an inch or two so that the base of the penis rubs against the woman’s clitoris.

Here’s a little visual aid:

In one study of women who were unable to orgasm from missionary sex, published in the Journal of Sex and Marital Therapy, those who learned the CAT reported a 56 percent increase in their orgasm frequency.
