I have recently gotten back with my boyfriend. We've had an on-again, off-again relationship and with each split, his behavior becomes more and more disgusting to me. I've heard rumors that he HAS been with someone else and he admitted (after lying about it the first 3 times I asked) that he kissed someone.
My concern is an STD. My body has had a unique reaction to our "sessions." Not during, but afterward. I've also been going through some female issues so I don't know if this is simply a coincidence or I'm "infected."
My question: Is a man obligated to tell if he has been with someone unprotected while NOT together with his girlfriend?
