I think I heard years ago on the History Channel that after Spartan boys were taken away from their families for military training they were paired up with an older man who would mentor and have sex with them. Then when they came of age and were married off to a woman they were so used to only having sex with men that their wife was supposed to shave her head to look like a boy when they had sex for the first time.

Is this sensationalist revisionism or is any of that actually true? If so what are the sources for it?
