@Secluded Lake,
a) He's not your boyfriend. Don't call him that. He's a guy who wants to kiss you, etc. and you don't want that. If he is bothering you, then tell him to cut it out. Don't couch it in dating terms.
b) You may be asexual. It's nothing to be ashamed of.
But either way, why are you hanging around with someone who you are incompatible with? Be kind and tell him he has no prospects.
