He says he doesn't want to have sex anymore... (Update)

I brought the topic of sex up once more on our way home (check my previous post) since I was slightly intoxicated so not all I was saying would be taken seriously. First I offered him road head which I thought would be irresistible to any man but he kindly declined. I asked maybe once or twice to make sure he was sure and he said yes. I then get proceeded to ask more about his "no more sex" pact. I couldn't help but to think that there was something I was doing wrong because he just not the type to give up sex for a while (we haven't had sex in about 3 weeks+) So I had to ask if there was something I wasn't doing that makes him feel that way and he said no. He said that he's just gotten used to it so much that he's just not in the mood anymore. In a way I understood what he was trying to say. In the beginning of our relationship we would have sex nearly once a week every week for about 3 months straight. Then school began and our time together became a little bit more limited and we were more focused on time with eachother than actual sex (though we would squeeze time for that sometimes). He's not one to lie to me so I don't think I have reason to believe I'm doing anything wrong. We've experimented with different positions, bondage, ice, etc. (we were talking about experimenting with toys and role playing before this). He's still very intimate but now I'm frustrated because now I have to involuntary hold off on sex too until he finds himself in the mood again . Is there anything I can do? Do I just ride it out? Do I become more of a tease and how would I do that? Should I be worried about the fate of our relationship because of this?? I have so many questions!!!
