I've read several articles, one by Andrew Sullivan that claim Benedict is probably gay. His personal secretary is called "Gorgeous George" in the Vatican. There was a priest on CNN saying over 60% of Catholic priests are gay. So it's certainly within the realm of possibility that Benedict is gay.
Of course they are. Any straight young man, especially one who has already experienced pussy, would know that heterosex is too high a price to pay for some silly god wish. I wager that most men who enter the priesthood do so out of some sense of self-loathing of their sexuality.
