I'll try not to ramble too much here, because most of what I want to say has already been covered; Like Nubian & Irish, I sense that you have some deeper issues to deal with, more's the pity you're having to deal with an insensitive prick now, too! Let's see, he brings up a 3sum w/your friend in the middle of sex, cums in your mouth w/ no warning, embarrasses you about whether you swallowed, leaves you hanging... no, I'm not being unfair to him at all, he's an asshole! Now, I won't tell you to dump him, but you've gotta see some ugly trends developing here... & I think you already know what you must do... it bothers me to see you mistreated, and especially this way, cause my answer to your question is I do enjoy cumming in a woman's mouth, but it has to be on her terms, not mine.
(Yep, I think I just repeated what everyone else said, but I had to put it my 2 cents anyway)
