let me expound further.
as someone who is pro-sex, and thinks that sex is usually a good thing, and who thinks that sex can serve a variety of purposes for a variety of people, i also strongly, strongly believe that we make our own rules for sex and those are rules that we must be able to live with. so, if one's religion were the sole reason why one would avoid sex before marriage -- assuming, of course, that marriage is an option for you -- and this eats you up at night, and you hold on and hold on and then you do get married and it's a massive disappointment, or you're with the wrong person, well, then i'd argue that you really should have been having sex before you were married.
however, if one has strong convictions as has been alluded to here that are influenced by, but not solely dictated by, one's moral upbringing and arrives at the conclusion that they shouldn't have sex before marriage for rationally thought out reasons x, y, and z, then i'm all for that. and that's a pro-sex stance, because the definition of actually being pro-sex is that you believe that sex is a good thing in life, that sex is something that people should enjoy and that will bring you joy, but only YOU know best how it can function in your life as a good thing and only YOU know how you will enjoy it and how it will bring you joy. one can be pro-sex and yet believe in abstinence.
i did beg an answer from nathan because i felt like he was being coy, almost as if he was trying to talk to the kids in their own language and construct a pro-abstinence message out of a position of assumed sexual experience, but which to me rang fairly phony because it assumed that one -- or, really, women (who need our protection) -- is always and only driven to fuck by the worst of motivations, and be left with the worst of consequences. i just don't think that human beings are that simple, and i don't believe that women who are out to have a quick fuck one night are driven to do so out of some twisted notion of feminism and then walk home trying to feel empowered but their essential virtuous womanhood conscience keeps telling them that they really wanted that man to love them and they're looking for something that they won't ever find and what they did was wrong. nor do i think that most men thump their chests after a one-night stand, trying to push aware their essential virtuous manhood conscious that keeps telling them to "do right by your woman."
some of this thread -- like some of the sex addiction thread -- felt analogous to intelligent design, whereby a specific set of moral values takes extreme examples and represents them as typical experiences in order to justify and thusly "prove" said moral values (i.e., "studies show that the best place for a child is with a mother and a father"). does that make sense?
and i'll also admit to being a bit leery of this stuff here based upon a show i recently filmed where it very, very much felt like clinical psychology had been perverted to fit a specific agenda, and fairly natural behaviors and impulses were quickly and forcefully pathologized because they didn't adhere to this unspoken but understood belief system and this was presented using (deceptively) clinical language and the patient was taught to suppress and control his behavior rather than try to understand what was driving him to do things in the first place.
