Need help with word choice, advice from any is welcome but writers are especially helpful!?

OK, I'm trying to come up with a certain word to describe a feeling. Have you ever had a crush and stared at their picture on facebook or myspace? That feeling you get, like you're doing something wrong but you don't want to look away? And that warm feeling that kind of flows through you?Need help with word choice, advice from any is welcome but writers are especially helpful!?
This sounds like a crush. It sounds like an inftuation. I think the word ';infatuation'; is a more mature way of referring to a crush. The word ';crush'; may read as a bit more light-hearted (which may be exactly what you feel for all I know), but as far as quality word choice, I would suggest infatuation.





I hope this helps! =)
