<human>: Summarize the given text in a few sentences.

My boyfriend (20) and me (F,21) have been together for 6 months. We're a college couple and about 3 weeks ago we moved back home for the summer, about 2 hours away. For the past month, a few things have been rocky in our relationship (he was messing around with other girls online and such), but we are trying to work through those problems and doing pretty well, I thought.

Recently he's become SO paranoid that he is not adequate enough for me. He asks me if I think about other guys when I pleasure myself, and I don't lie to him; once in a while, I do, and I know he likes watching porn and that he thinks about other girls, and I'm not really bothered much by that, because I know he loves me. 

Now that I've told him this about myself, he's freaking out and asking me not to think about any other guys ever and to only think about him when I masturbate. I don't really think about other guys much to begin with, but I just thought this was really weird and kind of an unreasonable request to ask of someone. Just because your SO thinks about another person doesn't mean they want to cheat on you, don't love you, you're not enough for them, etc. and I try to explain this to him, but he doesn't seem to believe me.

Am I crazy? Is he crazy? Is one of us being unreasonable? How can I calm his fears, or should I get out now while I still can? I've always been faithful to him and I don't think I've ever given him a reason to worry about me looking for attention from other men.
