never orgasmed

I lost my virginity to my amazing boyfriend 8 months ago, and we have been having sex frequently ever since. I love him to bits, and having sex with him makes me feel great! I feel close to him and connected... however, I don't think I've ever orgasmed. Ever. Not on my own (I don't really masturbate since I don't enjoy touching myself), or with him. And he's tried everything! He goes on for a long time, he goes down on me.. he really has tried.
