I can answer that one, actually. Technically, the bible only condemns homosexual sex. All sex outside of marriage is sin, and marriage is between a man and a woman. This is why Claudio is against gay marriage, btw.
Homosexual relationships are ok so long as those desires are not acted upon. Claudio, a virgin (assuming he didn't rape the cat), could still technically get into heaven. I say "technically" because I don't imagine that the lord is exactly fond of his constant violent threats and his propensity to tell people to kill themselves (which would be committing a sin).
