I've never told anyone this, so here goes.
Sprained ankles turn me on. They are the fucking sexiest thing ever in my eyes, but of course it also depends on the girl who has it.
So, my question to you is this: how would I go about asking my girlfriend to incorporate this into our sex life? Not actually spraining her ankle or anything, but just pretending. I realize this sounds weird as hell and I don't want to freak her out. Help a /b/ro out.
