Should I add my crush on Facebook?

[eruduru]

I have a crush on this guy, I just recently even found out his name. We go to different parts of my high school and every time I see him I die inside, hahah. We walked in at the same time last week and I held the door for him, and he said thank you, and I swear I almost screamed and jumped around, lol!
We're very different people though, I'm a really shy, anxious, short, chubby nerd, and he is a tall, bodybuilding, weed smoking guy who wants to join the army.
I just found him on Facebook and flipped out, lolol. I looked at his interests and stuff, and he has some of those pages liked, like "sex" and stuff for interests/activities and that worries me a bit, ha.
We don't have any mutual friends and I've never actually spoken to him or anything... He has over 800 friends though...
Should I add him? Maybe, perhaps?? I'm worried but I really like him ('':

thanks!
