trouble getting an orgasm??

I used to watch a LOT of porn, like every time I masturbated I would watch it. I didn't think it was a problem until I noticed that I couldn't get wet without it. I could be kinda turned on and then when I get myself to orgasm, then I'll become wet. But before my orgasm, I don't get wet?? My boyfriend is able to get me wet and really turned on, but he isn't able to make me orgasm. I don't believe he's the problem, he's really good at oral sex. We never had sex before, so I wouldn't know if I could orgasm that way. Do any of you have any suggestions??
