I don't think this is normal

So, I started masturbating when I was around 12 or 13, and I never felt much pleasure from it. I'm 15 now, still a virgin, and I still don't. I don't know if it's because I'm just to comfortable with it now, or maybe there's something off down there. I think that maybe if my boyfriend tries something it would be different, considering he turns me on rather quickly, but we've haven't gone that far yet. So I wouldn't know. Thought? Ideas? Suggestions?
