Too much porn??

So I'm 19 and a virgin and I masturbate to porn at least once a day (sometimes 2 or 3 times) but I've found that I can't masturbate without porn to focus on. Without porn, I just get really distracted and I can't get into it. I'm worried that when I finally have sex with a guy that I won't be able to cum. Do you guys think I have a problem???
