Does my friend like me?

I'm a guy and I have a friend that I've known for three years now, and at first we started out on bad terms, but eventually we got rid of the bad blood and became friends. I appreciated his friendship because there is a male friend deficiency amongst my friend circle. Anyway, he is one of those people who I say exhibits what I call jock humor, which is grabbing and crotches, saying suggestive things, and being overly physical in a joking manner. Well I hadn't seen him in two years, and when I saw him again his jaw dropped. For the first few hours of our reunion, he was checking me out; scanning my body. I even caught him looking at my a lot. There was another time when we were swimming, and we made intense eye contact in the pool. He licked his lips and slowly began making his way towards me. He got within a few inches from my lips when some of our other friends started swimming towards us and he nervously splashed me. He asked for my number and his phone isn't turned on at the moment so he told me to write it down. I asked him, "How are you going to keep up with a tiny piece of paper?" and he tells me, "Don't worry, I won't ever lose YOUR number (emphasis on the YOUR) He is also always looking for a reason to be around me and touch me. He even turns that whack *** handshake thing into a prolonged moment to hold my hand. Now I should mention that I'm not OUT, but not because I'm scared, but because I feel I don't have a PREFERENCE, and my ORIENTATION...well that's just something so other people can stereotype and group me. The thing is, this isn't one of those "I'm gay and I think my straight friend likes me" posts, but it is that my friend might be pursuing me whether or not he suspects I'm into guys as well... It's complicated. Feedback?
