ACE...?

the ace dilemma... what do i do if a friend asks me out? sure i like him. i wouldnt mind dating him... that is unless he wants to..yk... which is expected i suppose, a normal step in a relationship. but what am i to do? things of that nature dont interest me. i dont mind them. i dont think theyre gross. i dont think no one should do them. i just mind it if its ME. i think its gross if its ME. i think I shouldnt do it. ive never wanted to and tbh i dont think i ever will. ive never thought of ANYONE in that way, ive never even LOOKED at anyone in that way. its just not something i do. but what should i do? reject him? i dont want to but... i would do anything to avoid the awkwardness this conversation would bring... and i will assume hes normal. i will assume hes just like the rest. and ill assume this is something he needs, for a relationship, and i know its not something i can give.
