My boyfriend and I have been together for about eight months and the first two times we hooked up, he went down on me. He offered once more about two weeks later, but I had my period, so it wasn't good timing. Since then he hasn't offered and changes the subject whenever I bring it up. He does, however, ask for blow jobs, and I offer too because I enjoy giving them. I've asked a few people for advice about this but they always say "quit giving and he'll start giving." I have asked him if there's a problem with the way I taste and smell, but he said that's not the problem. I don't know what to do. We live together, have a car together, and have a dog together. This is our biggest problem, help!
