For tomorrow: Why Sex is Taboo almost in every civilization and every society? Why every religious leaders like Buddha, Jisus, Mahommad discouraged the sex and encouraged the celibacy? Why people followed them? Were all of those people at their time dumb? Or was that a kind of fashion? Is sex a biological need? Why modern day scientist, who are realistic and result oriented, don't advocate for free sex? How the concept of virginity introduced in the society? Is virginity only for women? What for virginity is? I will be answering these questions from my understanding.
