I've never gone down on anyone. And recently my bf and I went on a trip. I was a little under the influence and started kissing his stomach and began touching him and sucking on his foreskin but I didn't have the guts to fully go down on him. I think it's gross and I just can't seem to do it. We tried to do it again the next day in the showe and I still couldn't. Anyone has had problem giving head? Or how do you even give head? Tips for first timers?
