well, the higher the testesterone, the higher the sex drive. the younger the male- the higher the testerone. hence, constant thoughts of sex. It's not immoral, it's biological. Most everyone wants and prefers love, and love making over sex without love. But since sex isn't immoral and is a choice between consenting adults, I will have it when it suits me and is a mutual desire between me and my partner. I am not going to let me not having a girlfriend or boyfriend deprive me of my natural pleasures. With that being said I would still prefer a monogamous relationship, but why do so many people try to turn human nature into some moral competitiion? it's not like these people are advocating violence or hatred.
