There's something that needs to happen before we start talking about removing contraception from the "sin list." The Catholic teaching magisterium must finally acknowledge that sex isn't only about conceiving a child. This is almost acknowledged every time old infertile people marry in the church. I once asked a priest why the church would marry people who are clearly beyond their child-bearing years and do you know what he said, "to allow for a miracle." I kid you not. Seems to me if God can create a miracle and suddenly make an old woman fertile again s/he should be able to make a lesbian pregnant from, I don't know, the Holy Spirit? Or perhaps a gay man will miraculously be able to bear a child in a womb that God could suddenly create in him. But no, that would be foolish so we can't allow gay sex. Getting past that barrier would also remove masturbation from the sin list and also allow every straight couple to enjoy sex without worry. But I'm not holding my breath waiting for that.
