New to the above and in the gay world I'm a top, and trying to do some exploring. The issue I'm finding is that (as I've tried using a few) unless I'm tensed up, at some point they seem to always get pushed out. It's like there should be a way to 'lock' it in without having to hold it there with a hand. Anyone know of a specific type I should try so that it stays in place? BTW, my weighted nut swinging low and hitting it feels pretty good.
