Relationship Advice

So I finally met this guy that I've been dying to meet... And he reminds me a lot of a few other guys that I was sexually interested in a while ago... and I got my way with one of them last year and felt really sad that I never saw him again ;3;
But this guy... the guy I met today... I saw him previously.... NAKED.... .///. and at that time, I was drawing him naked.... but I couldn't help but look at all that stuff down there... and had to go to the bathroom because I got so worked up >//<

And he's in one of my classes now...
and I really want to hang out with him... I talked to him after my class, and I got really nervous talking to him... my heart dropped... my stomach got fluttery... and I tried to talk as well as I could stand... >//<

I also looked for him in the library, but he wasn't on the second or main floor... so I went downstairs and I got worried that he wasn't here and left already...

And when I saw him he was playing LOL online, and I told him that I was getting worked up not being able to find him... I had to leave for a while to cry because ......
I JUST met this guy... and I already want to be with him.... Like... not joking... I have a feeling like I ABSOLUTELY need to be with him... >///< and I don't know why.... it's really strange... I fall too fast and want so much... I just want to see how it works out this week.... I'm getting so anxious around him... but then... when I started talking to him and getting to know him better... it feels not so bad anymore... but I still have a lot to discover about him...

It just feels like... I'm already obsessed with him, I feel like I NEED him... even if I think he may not be a good guy sometimes... I'll just have to hang around him some more to find out >///<
