Well I guess you just shoulda thought about this before you broke your vagina masturbating, shouldn't you? Jesus doesn't like people who diddle themselves. Now you're reaping the consequences.
You could also wrap a face towel around the you bottom of the cock to act as a speed bump from deeper penetration. Or do doggie style why on your stomach, if you don't have a flat ass it's create a bit of space so he can't go as deep....hope that helps.
Yeah, how is it when u lay flat on your stomach? I love doing that shit and its never a problem for them. I'm drunk by the way. Sorry to be straight foward. No boner going on here.
You should get on top-that way you can completely control the action. It really might help. Also, maybe he could lick you a lot before you start having intercourse-it might help to get you really lubricated
