I don't understand how people say you can't enjoy sex if you don't masturbate. Masturbating is boring and for a lot of people, it makes them feel pathetic. That's how it was for me. On topic, maybe you should just have your bf use a virbator or a small d***o on you first? That way you can get used to it and he'll still be sticking to his ideals. I wouldn't think he'd have an issue using a toy on you and you'll feel a lot more comfortable with him doing it to you instead of you doing it on your own.
