My boyfriend and I have been going out for almost 7 months now. When we first started dating, we were having sex at least once a day. However, in the last few months, we have been going 2 sometimes 3 weeks without being intimate. He uses excuses like "my head hurts" or "i'm too tired" and completely rejects me when I try to initiate. As far as I know, there are no changes to his lifestyle(we live together). But I have noticed changes in other aspects of the relationship as well. For instance, he used to not go anywhere where without me, now it seems we only go somewhere together when i say i want to go. Also, I read somewhere that a man who is really in the relationship will not jump up right after sex, which he had started doing when we were having sex. He has a history of getting "bored" with a girl and moving on quickly, but swore to me he wasn't doing that. He is 26, I am 23 and there are no medical conditions on either part. I've tried talking to him about it, but when I do, he makes a joke about it and changes the subject saying that he "doesn't know" why we aren't intimate anymore. I don't want to pressure him and I don't want "pity" sex either. I have a very strong sex drive, and he is fully aware of this, but it doesn't seem to bother him. I have laid awake many nights, crying, trying to figure out what I did or need to do to make him want me again. If anyone can help me, I will greatly appreciate it.
