I'm sorry, I don't think I explained the situation very well. We only end up sleeping together occasionally. We're really good friends and spend most of our time hanging out together and hanging out with mutual friends, including my family. The sexual stuff is really just something that happens, and isn't why we hang out. I don't want to ask him yet for a couple of reasons. One is that I'm not sure I want to be in a relationship with him based on how controlling he can be, and how he completely changes his personality. And another reason is that college is a couple of months away, or less, and I don't know if it would be a good idea to start something with somebody who's going to be 5 hours away from me...
