Well I know when I think of the other person it's the connection within the act not just the actual act itself. Which you said is a big piece you're missing. Maybe it's finding the right guy? Hard for me to say since I don't know a lot about asexuality buuut it is perfectly okay to be asexual. Have you told your bf? I think he will start to wonder eventually and explaining it to him will help him go okay I get it now. This is a way around but I can't say for sure if it's healthy or not long run - you could let him watch? Sorry I don't have better answers but at least you get another perspective. Hope it helps
