I used to do gymnastics when I was younger. I don't anymore, but I still practice my splits and straddles from time to time. I've never told anyone this before, but it makes me horny to do them. I don't know what it is...maybe it gets the blood flow going down there. Or maybe having my legs open all wide like that reminds me of having sex. That's why I like to stretch and masturbate at the same time. It's my secret to having the best orgasm I can have by myself.
