Ake, I'm wondering if you have read Dr. Herek's article thoroughly. Dr. Herek would agree that there is selection by gender in the abuse of children and youths:

The distinction between a victim's gender and a perpetrator's sexual orientation is important because many child molesters don't really have an adult sexual orientation. They have never developed the capacity for mature sexual relationships with other adults, either men or women. Instead, their sexual attractions focus on children – boys, girls, or children of both sexes.

So, certainly some molesters prefer boys and some girls (and some both) - but their focus is on male and female children, an orientation quite different from an attraction to male or female adults.If an adult male is drawn to have sex with a female child, would you call that normal?
