Is he interested, just teasing, or what? ( pretty long story, please help) It's all so misleading !?

My issue is this ; I really like a senior in my highschool, and he is completely difficult to read. Last year, he started teasing me about my hair, which is really curly and perfect ringlets. He always made an effort to pet me like a cat, and stuff like that. This year, His fourth cl is next to my locker, so now we speak on a day to day basis on limited conversation. One day he stroked my neck for a few seconds, and I got really embaressed. He's nice though, and stops if I ask and all that. But what confuzes me is THIS! in 2007 , i made a youtube video that was about coming out day, and it got spread around the 8th grade, so I deleted it. Now, yesterday, me being in 10th grade, he ims me on facebook and asks for the video link. I explained it was removed. He also asked me if I'm really gay, and I said yes. Iu asked if thats why he messes with me, and he said that he had no clue I was gay until somone mentioned the video. He then asked me if I thought he was attractive, and if I would kiss him. I answered truthfully, but totally dodged the kiss question. Then, we discussed if I've kissed any guys, and I told him no. I also said that no one has dated me, so I clearly haven't . He then said that you don't need to be in a relationship to kiss a person. Thats basically it, and what confuzes me is why i he so interested!? He's an idiot, but hes really nice, so I''m unsure if hes just messing with me. Also, over the summer, his facebook said interested in men, but now his myspace and facebook have it hidden so you don't know what he's into. sorry, this was so long. Thank you, so much.
