There’s a weird idea that’s been out and about for hundreds and hundreds of years that it’s normal for a female partner to “just lay there,” — and disturbingly, this has been a common complaint from heterosexual male partners about women — or to be totally unengaged in sex. The thing is, while that may be common, it’s anything but normal. Someone who wants to be having sex with someone else — who really wants to, which is the only time anyone should be having sex — isn’t just lying there, silent and prone. They’re clearly engaged, and clearly and actively participating in the sex they’re having.
