Hmm... I have never been in this situation myself... sweatdrop I lack in the girlfriend department, I am a guy just to let you know sweatdrop Anyway that is besides the point.

Unfortantly very few guys understand Asexuality. My dad for instance veiws my Asexuality as me hiding Homosexuality. I am sorry that your boyfriend does not see eye to eye with your veiws. The best thing you might be able to do is explain to him your beliefes and way of life. If he does not understand he might not be worth keeping around. Seems he would only want sex. Unfortantly I have seen my dad use this tactic. He wants sex but his female friend wants a relationship. So he spews out some crap about how he can't have a relationship without sex or about how sex is a biological need like eating or drinking water. Here why he wants to have sex. See if there is a deeper meaning to his wants. Sit him down and have him explain why your relationship can not be any good without sex.

Personally I could not live in a relationship that involved more than hugs and the occasional cuddle. I see it as taking away from love and friendship in a relationship. Though I cannot speak from experience.

My last words of advice: love is about comprimse.
