I was in the same position. Never been really attracted to guys until this ONE guy came along. I really wanted to pursue him. So I made sure to talk and joke with him a lot, and sort of get a vibe of what he thought of me. When things seemed to be going good, I blurted out "I like you." and confessed it all. Guess what? He liked me too and everything is working out perfectly. Sometimes you just have to take a leap!
