Pedophilia is not a genetic thing, homosexuality is under study but suspected to be. There was a study made (I'll find the sources and post them asap) that a range of men were made to smell women's and men's sweat. Results were that straight men prefered the women's sweat over the men's, whereas, the homosexual men prefered the men's sweat over the women's. Ofcourse none of the subjects knew who's sweat they were smelling. It supports the theory that there's something biological about homosexuality that's triggered by the enviroment.

I'm not always right, but I'm never wrong :P - Garfield
