The one chronicler who would actually know what went down in the barracks (on account that his sons went there) flatly contradicts that. Aristotle blamed a lack of homosexuality and pederasty for the "poor" culture of Sparta compared to Athens and Corinth. There's also psychological backing for Sparta not enforcing mandatory "spear practice" after dark. Their culture was about as non-misogynistic as it's possible to be in ancient times. Women could do what they wanted, inherit from their parents, were economically more important than men (because ya know they were in the barracks so often their wife had to take care of the estate) and didn't married until they were old enough to "enjoy sex" (that was actually a law). Athens, which was filled with pederasty and child molestation was at the opposite end of the spectrum, to the point that if a woman got raped her husband legally had to divorce her.
The kicker? Modern psychological research indicates that men who were sexually abused as children are more likely to be misogynous when they grow up.
Ah, I knew all that about the women, they were also encouraged to compete with men at sports and all that malarky. By all accounts (Discovery Channel, not Channel 4) the sexual nature between mentor and mentee was far from sexual abuse on an adolescent, just accepted practice between what passed in Greek times as mature chaps. Perhaps Aristotle's problem was that it wasnt a free for all? Besides the tough nature of Spartan Women would've made mysoginy very difficult. Especially from Men who didnt see much of them.
Or perhaps your right and bumming was kept at a premium and I've been lied to not only by that History Program presented by Historians but my overly touchy history teacher also. That'll be annoying.
