Look, Dennis, you only have to look back to the ancient Greeks and their pederast culture to see that men can be taught to engage in and enjoy sexual relationships with other men.  It only makes sense that it can go both ways, no?  Or were there just more men born with same-sex attraction in Greece?  The whole immutability of sexual attraction theory is a lie, so the question is how is society best served for propagation and prosperity?  Apparently the Greeks figured out that pederasty wasn't the answer.
