Take ecstasy, save your relationship - Salon.com
"Women naturally product oxytocin bursts during sex which promote long-term emotional attachment to the man she's banging. This is nature's way of promoting an ideal two-parent family structure that is likely to endure at least until the children are able to start taking care of themselves.
But what we see now is that women spend so many years riding the cock carousel and fukking dozens of men that their brains become less sensitive to the oxytocin bursts they receive from sex. So over time, women gradually lose the ability to emotionally pair bond with the man they're having sex with. So the poor b*stard who settles down with the early-30s veteran carousel rider has no chance. As soon as she pumps out a couple of kids, her brain has no more use for the guy. Her emotional bond with him was so shallow from the get-go because she spent an entire decade getting pumped and dumped by a string of alphas. Her oxytocin receptors are shot from the constant highs and lows she received with every new pump and subsequent dump.
This is another reason why virginity was so highly valued in the past (and still is today by some). Beyond the guarantee of paternity, marrying a virgin greatly enhanced family stability. In the old days, the idea of marrying today's average carousel rider would have been as absurd and disgusting to most men as marrying a prostitute. But that's basically what men are doing now.
It's terrifying to realize that the average Western girl today has the emotional brain chemistry of a prostitute, and is so emotionally damaged from years of carousel riding that she needs ecstasy therapy to even have a chance of remaining emotionally bonded to the father of her children."
