My spouse of 15 yrs recently started get rough with me during sex. He will bite my breast and other places . I have showed him the bruises and he said he was sorry but will do it again . Could he be having an affair or taking his anger out on me? What should I do?

What does this have to do with having an affair??

Why don't you talk to him and ask him what's up.. you need to communicate and tell him that he's hurting you and you don't like it..

I can understand the suspicion of an affair, as his sexual "maneuvers" have changed after 15 years. It could be an affair, but it could also be that he's trying to spice things up in bed... perhaps trying new things, being aggressive, etc?

I do agree with plonak that you should talk to him about this. Not simply just show him the bruises, but sit down and have a chat, see what's going on.

Yes, sounds more like perhaps watching some porn or talking to other guys as to what to do to make things more exciting, Next time he bites ( and you are not into that) stop the sex, after a few times of having the fun stop, he should also get the idea. But only if he continues after you have talked about it.
