I've been in a relationship with a man since April 2010. We live together. We're both in our 50's. In the beginning our sex life was AWESOME. But slowly it's dwindled down to nothing. We haven't had sex for 5 months. I work nights so we don't sleep together every night. But when we do he cuddles affectionately but that's it. Yes I've talked to him several times about how this bothers me and he blames it on the fact that we're both working alot of hours and are often tired. But Tony that's just not getting it for me because we've been on vacation for over a week and still no sex. He's good to me otherwise, he tells me he loves me. But I just don't understand what the problem is and he won't tell me. What should I do? I don't think he's being unfaithful am I being naive?
