My Boyfriend says it's alright to talk about sex with your partner, if he has feelings or emotions towards it and wants to express them, he should be able to do so. But here's the thing, I have asked him to respect me and my beliefs, and I ask that he doesn't bring up how he's sexually frustrated, and he brings this up on and off as of late. Each time he brings this up, it hurts me, when all of the previous guys I have been with, never mentioned it, they respected it and never brought it up. I don't know what to do, but it hurts me when he brings it up. What to do?
