Let me get this straight. Most Naruto villians and characters were basically Virgins?

Madara never got married, Obito couldn't forget the crush he had for Rin for almost 30years, Orochimaru wanted more power is whole life?
Other mentions;
Tobirama, Kabuto, Izuna, Gai, Sasori, Hidan, Nagato, Konan, Karin e.t.c
Why Kishimoto at least Lord Madara shouldn't had died a Virgin that's illogical in my book.
