Badfish,
Lots of men have sex who never want children and take steps to never have children (vasectomies, condoms, etc.) Even more women have lots of sex and never have nor want children. Everyone wno procreates has a lot more sex than just for procreation. It's called fun. Pleasure. Think about it. If the planet was full, governments would have no other choice but to limit procreation. It's already happend in China and other places. There will likely reach a point on this planet where bringing children into the world will be tightly regulated for everyone and perhaps banned for a while. But people will still have sex.
And if procreation is the only reason you think people have sex, I guess, like the GB/FDS, you think only vaginal intercourse is 'appropriate.' (I effing hate that word). So no oral sex???? because that wouldn't be the primary purpose for procreation now would it? That's only about pleasure. I guess you would make a good member of the GB.
You have a lot to learn. Open and expand your mind. Try to stop thinking in the enclosed black and white world you have lived in for so long. And your smart ass response about admitting you were wrong just shows your ignorance. Try some humility. Learn something.
