The one time I tried it she said, "What are you doing?"
Seems pretty useless to me. If your dick is so soft you can slap somebody with it, you're probably not quite ready to fuck. Get hard and go fuck.
Dude I think you are misunderstanding the post he means slapping a girl or Guy with your erection during a blowjob
What do you all think about slapping your partner's face with your dick or being slapped by one?
Most of the people I've been with like it when I slap my dick on their face, but last night the girl I was with got annoyed at me for doing it. Of course I stopped, but its the first time someone was annoyed by it. In fact, a lot of guys seem to really get turned on when I slap my dick hard against their face.
