Armok, you never cease to amaze... I have no problem with celibacy as a personal choice, or even as a joking excuse for not getting laid, but trying to claim that it "helps your scientific capabilities" just floored me. And it's hilarious down here.
Umiman, your elderly status has very little to do with whether or not you agree with imbeciles on the net. Frankly, I'm surprised that you of all people would get caught up with the "morality" of sex, but whatever. I guess I just don't know you that well.
Personally, I can agree fully with kicking morality out of sex entirely. Common morals have a funny habit of screwing things up for people. However, I do not agree that fully casual sex without repercussions is possible. At least not for a few more years.
We're just not set up properly to fully remove the intimate aspect of sex yet. And whenever we share our deepest intimacy with someone, we feel uncomfortable if our partner does the same thing with someone else.
It's like telling someone your greatest secret. You expect them to respect the intimacy of the moment and not spread that secret. If you know that they share an equal, or even greater, level of intimacy with someone else, then the security of your secret is compromised (I mean, honestly. Think of how many secrets you've been told, and how many people who are very close you've told them to. Because of the intimacy, you think you can trust them. But look what happened to you).
I may have rambled out of line in that analogy... It's always disturbing when I manage to confuse myself about something.
Anyways, I'm not saying there aren't people out there who can't do this. They certainly exist, it's just that they're few and far between. This is by no means a common position. I think you'll be very hard-put to find someone who can have truly "string-free" sex with their close friends... There will almost always be complications.
Realize that it goes against a very, very basic sexual desire to fully accept a sexual partner getting it on with someone else. We'd have to get away from our fundamental animalistic ancestry in order to really get into the "free love" swing of things. Again, not saying it isn't possible, just saying that it isn't particularly common.
But then again, I'm not getting any either, so I guess my post is made utterly baseless. So it's your call umiman... Whose unproven hypothesis do you want to believe in?
Pre-Post EDIT: Holy Shiite, seven posts while I was typing? I must be getting slow.
