God I had to join, just to respond to this!
OP talk to your partner about what he said and how that made you feel, I too would be furious, if a conversation like that happened in the group setting you describe. I talk to my friends about things and my husband, but wouldn't be so open in conversation with a best friends husband there.
However only you know in your relationship and friendships what as a couple you talk about and what you dont. Im assuming the conversation was around sex, and he didn't just randomly say it.
Maybe he just got carried away, he made a mistake? Drunk a bit too much and got carried away? None of that makes the comment right- but you need to talk to see how you feel about his response.
If he doesn't like oral sex, he shouldn't feel obliged to provide, all the time women are being told, to only participate in what they feel happy doing, that should be the same for men!
If this is the case and you still like sucking his cock, carry on, you shouldn't not do this just because he may not reciprocate, we all like different things and a mutual relationship should ensure all are happy.
The comment that he a misogynist, based purely on the comment above and without knowing anything else- I mean WTF???
If you currently dont want sex as his comment has hurt you and you dont feel the connection currently- dont have sex. But to with hold sex to prove some kind of point. Is in my opinion a little childish.
Im aware of man people that dont like the sent, that doesn't make him crazy. Some would get on with it, as its not that bad, some dont want too.
TALK!
Talk about how it made you feel.
Talk about how you were feeling before the comment.
Talk about why he has never said this before.
