Please take the time to answer this question seriously..?

First, let me start off by saying I'm a very shy and timid person. I'm not the type to go over to someone and just start talking to them. So anyway, I'm a freshman in high school, and I recently just got off a really hard heartbreak. But anyway, there's this guy who is my friend, I guess, he's a total flirt and he's sort of annoying but I'm growing a liking to him. I don't know if it's a friend liking or is it a romantic liking. But I won't say I'm in love because I honestly don't know. I've only been in serious love twice. One in elementary and it ended in a bad way because I never told this guy how I felt and he left when we reached 7th grade. Another is just recently when I had this big crush on this junior at school but he has a girlfriend and I don't want to mess with that. I'm still not over it but it's healing. Back to the subject, you might ind this totally wrong but he always touches me. I mean not inappropriately. Like not my chest or or anything like that. I have two cles with him and he sits behind me in one and every now and then, don't take this wrong way, but he gives me mages. I know it sounds wrong for ninth graders. Trust me, I know. It doesn't particularly bother me, it's just the thought of what my peers think. I mean in high school, if something like that happens, you could immediately be labeled as a wh*re. I don't want that. So people ask me if I like him and stuff but I don't know what to say but "No I don't! Stop asking me!" Like I said, I'm shy and timid and get embarred over things like that. So this morning he was like, "Chris said you don't like me. Is that true?" So I just hurried and closed my locker and went to homeroom. He still talked to me today afterwards so...I don't know. I'm just confused. So I noticed this a few days ago when people really started asking me. I don't get a fuzzy feeling when I see him, I laugh at practically everything he says because basically he's a cl clown, and he's not all that cute. But yesterday and today, I kept thinking about him and somehow he became so cute. Please help me. I don't recognize this emotion at all.
