Cogliostro,you can have your bigot views,there is freedom of speech. But they have no basis in rationality or science,and please don´t bother gay people with them. Sex is not about reproduction. Reproduction is a biological function. Sex is an act,and I don´t care why I have a sex drive. You can make the argument that we have the sex drive for the evolutionary purpose of reproduction,but to go from there and claim that sex SHOULD be about reproduction,is just a random dogma.
I have a child,and I am not planning to have more. I still enjoy sex. Mostly with women,but I´ve had experiences with men as well, and it´s all great!
Sex is pleasure,but can also be a deep connection, something spiritual even.
Your views are obviously based on religion. Religion is just stories for children.
