So they're targetting juveniles instead of women that they counsel? Don't think that quite adds up.
Sex drive is a powerful thing, certainly. The priest could avoid the priesthood - go have an affair with a parishoner - target a child or a fellow priest - or, honor the vow that they have taken.
If sexuality cannot be moderated by belief, men would never be able to stay in a monogamous relationship.
Maybe a life of celibacy attracts more homosexuals who want to repress their desires, than it does heterosexuals simply willing to make personal sacrifices to become a Priest.
