it's a tough call. there is a chance that he won't like you anymore and he'll just think you're weird, but the happening of that seems very unlikely. even if you believe he'll understand it, i'd try to avoid getting yourself into a tiny pickle and maybe wait until you are closer with him, if you're going to tell him at all. i'm happy that you're considering it, but it may make everything awkward. if the relationship is very lighthearted, i'd hold off a while. if you enclose a lot of information and have serious discussions, maybe it's all right. it depends where you are right now and where you'll possibly be in the future. but i raelly hope you figure this out!
