I've been with my boyfriend for over two years, and we have a great relationship. I love everything about him, and we get along mostly all of the time. However, for the past few months I have had basically no sex drive at all. He wants to have sex almost every night, and I almost always turn him down. He used to get really upset about this, but has since almost just given up and now only asks when he thinks its going to be a possibility, which is usually not often. I hate myself for always turning him down because I know it hurts him, but when I think of having sex it just always sounds very unappealing and I will do almost anything to get out of it. I try to suck it up at least once a week for his sake, but he knows I am not really into it so it still bothers him. Once we are having sex I really enjoy it and think about what I have been missing, but it doesn't help to get me in the mood for the next night. This has currently been the thing we argue about most, and is becoming a huge problem in our relationship, but aside from forcing myself to have sex when I don't want to, I am not really sure how to fix the problem. Some nights I am just tired (he often doesn't get home until 10:30 or 11 which is generally when I am getting ready to go to bed), but other times I am just not in the mood. I am only 21 years old and this does not seem normal to me at all, and I hate that it is coming between my boyfriend and I. Is there anything I can do to help? I am desperate to fix this...
