:smack: Not Lisslald, Lissla Lissar. Sorry.

Can we make a distinction here? Lust != sexual desire. Sexual desire is (according to orthodox theology, as opposed to what Sr. Virgo Perpetua may have told you) normal to humanity, and, in its proper usages, not at all sinful. (See “unitive” and “procreative” causes in Sarahfeena’s post above.)
Lust, on the other hand, is the perversion of sexual desire out of the intent which God (according to this theology) intended for it – to cause two people to be attracted to each other, marry, enjoy each other’s bodies, and make babies in the process. To want sex with the girl/boyfriend you love and plan to marry is not sinful; it’s the working out in your life of God’s intent to bring humans together in marriage. To want sex with the hot topless babe on the website the moderators would frown on a link to, with no interest in marrying but just a need to boink, is not an element of his plan. That’s lust.
I don’t necessarily recommend that anyone needs to buy into this bit of theology. But it’s only fair, if discussing Christianity and sex, to be clear on that distinction. God doesn’t have a problem with sex (though some of his spokespeople may) – but he may have a definite problem with some of the things we do regarding it. That’s the difference between desire and lust.
I can’t take credit for that…it was Lissla Lissar who made that distinction. It was basically what I was trying to say in my post (simulposted with hers!), but she said it much better than I did! I can see she is paying attention in RCIA! 
Don’t we have enough trouble with misuse of apostrophes?
Those just make the Baby Jesus cry.
It’s a little known fact that this is how the Virgin Mary actually conceived Jesus. You see, after she had finished… servicing her lover, as she was toweling off, she took a small amount of the leftovers and put them in the stove, so to speak. Still technically a virgin. And the rest, as they say, is history.
I guess that eliminates [del]butt sex[/del] anal intercourse.
We were given a copy of Naked Without Shame some years ago, by the friends who have been helpfully praying novenas for our conversion, and phoning us once a week to find out if we’ve converted yet. 
Now, I haven’t actually listened to it yet, but I’ve done a lot of other reading. I should get and read Theology of the Body, or get Mr. Lissar to read it.
Thanks for the complement, and Sparty, it’s okay, (almost) everyone gets my name wrong.
I like Poly’s summation of the difference between lust and desire.
That was the pun I was trying for, yes. I was beginning to wonder if it were the equivalent of the tree falling in the forest with no one to hear; thanks for picking up on it!
They’re fine, although he’d like Sister Mary to be more careful with her nails and teeth in future.
I can’t believe no one’s made this joke upthread before now. You guys are slipping. Must I do everything around here?
I was going to make the same joke, but you beat me to it. That’s what happens when I get behind in my SDMB reading.
“Fifty dollars, same as in town”
I am so going to hell for that
Which assumes, of course, that partners do not use pornography together…
Polycarp was making some good points in this thread, but that stupid pun wrecked 'em.
You’re getting overly anal about people making puns along with giving useful information in GQ, y’know?
I was hoping for a factual answer with no ifs or butts. :dubious:
