Is there something wrong with my (female) anatomy?

I am 20 years old and female. I have been masterbating ( I kid you not) since I was probably 4 years old? When I was younger, it was alot harder to deal with. I use to do it in my seat in class. Now that I am older, it has simmered down a bit. I put pressure on myslef with my hands or hard objects that I can rub against. I can do it easily with cloths on or not. I can do this as many times a day as I want to, but on average, I probably do it about 10 times a week now. Some times something I see on tv will turn me on, but mostly it's just this urge I get, and I have to do it, or I will be uncomfortable. I can do it with out thinking dirty thoughts what so ever. And I can get it done with in 1 minute. I have learned other ways of masturbation, like girls using dil-does, vibrators, or anything that can be put up there, but I don't get any pleasure from that what so ever. I lost my virgnity when I was 18, almost 19 and I don't like actual sex, it's painful for me and doesn't feel good or pleasurable, and I have tried all positions and have been with different men, so im assuming it's not the guys fault. I have had an orgasm from oral sex and it is completely different than the orgasm I get when I give it to myslef, but right afterwards I am completely turned off and discusted with myslef. Is there something wrong with me? Any suggestions, advice?
