Sex is the ultimate form of love. Without sex it won't be a happy earth. It would be an impotent one. That country you've mentioned are open minded country that I hope I live with. Freedom is a choice and they agreed to it.
The highest form of love is the spiritual form of love, and not human lust. Also there are many monks who practice abstinence not only from sex, but also from masturbation and they do not have impotence. Impotence, on the contrary, often occurs in a volatile world where there are always many bared bodies.
