Women do not owe sex to men.

True. And parents do not owe affection to their children.

Reading Elliot Rodgers manifesto has reminded me of the case of Genie, a girl who was kept in a room until age 13, given no affection, and abused.

No one owes anyone anything. But we can see that humans are social creatures, and that being deprived of affection causes severe emotional and mental issues. Genie is at the far end of that spectrum, and I imagine Elliot Rodgers is somewhere between there and the average person. No one owed him affection, no woman owed him sex, just like no parent owes their child affection, but somewhere along the line, Rodger's emotional needs were not getting met. This brings up the issue of involuntary celibacy.

The manosphere has blogged on this issue, of how the current social environment is trending towards more sex for fewer men, and women's heightened hypergamy driving them to choose only what they perceive to be the best of the best, leaving the average guy out in the cold. My previous blog post outlined my thoughts on the media instilling unrealistic expectations for men, to get a hot supermodel girlfriend by spend, spend, spending money on useless crap. Romcom movies often use highly unrealistic stories, and a lot of people seem to incorporate these fantasies into their expectations of real world relationships.
