Here's a list of sexual matters that trouble severely the Catholic Church.

Abortion (you are excommunicated)

Homosexual acts (it's okay to be homosexual but you are still objectively disordered and are called to chastity)

Any kind of extra-marital sex

Pornography

Any kind of contraception

Condom use to prevent HIV transmission

Coitus interruptus

Masturbation

Anal sex

Prostitution

Divorce

Gay marriage

Adultery

Lust (I think I may have called that impure thoughts in an earlier post)

Rape

Sexual intercourse that does not have the twofold significance of union and procreation (otherwise, you should be abstaining, so simple fun is out of the question)

As I say, a hefty list. The obsession with sex is even troubling the Pope. But he has yet to soften the stance very much on any of the above. Note that I didn't exclude stuff that I agree with just to make a baddie-only list. I recognise that some of these areas leave scope for interpretation and the exercise of conscience. I'm sorry, but that simply isn't good enough. The good Lord said let your speech be yea yea, nay nay. It's about time the Church followed the advice of the boss and let its members know exactly where they stand. No double-entendre intended.
