Though men do generate oxytocin, they don’t match the production levels in women. Men can easily facilitate oxytocin release in us (increasing our “rush), thereby creating more of a bond. It is harder for we women to facilitate oxytocin release in men.

Women, you need to consciously stick to behaviors that promote oxytocin production in areas of men's bodies (and brains) that yield beneficial effects. You need to nurture men in a way that keeps their hearts open.

Talking may or may not work. Usually it doesn't. Women need to talk when stressed. Talking raises your oxytocin. It doesn't necessarily initiate oxytocin release in men. Men don't like to talk. They feel obligated to ignore all the talk. They want to get down to solving the problem. Therefore, you need to raise his oxytocin without talking his ear off. There are other ways to score some oxypoints without making him want to ignore you. You need to come in under his radar.

Touching promotes oxytocin. This is why oxytocin levels rise in both sexes during arousal and orgasm. The estrogen in a woman’s blood magnifies and intensifies the effects of oxytocin. After orgasm you feels dreamy and relaxed, and possess an intense desire to continue bonding through cuddling, stroking, and talking. By contrast, the testosterone in the man’s bloodstream neutralizes his oxytocin—and with it the impulse to cuddle. Dr. Marianne J. Legato, one of the world’s authorities on male/female differences, tells women that men aren't being brutish when they pull away after love-making. "While the woman probably want to curl up and further cement the bonding that’s taken place, her lover feels no such urge and is already on the move, looking for a snack. The testosterone that makes him so sexy is neutralizing the chemical that makes you want to cuddle and whisper sweet nothings."

Conclusion:
The authentic masculine loves to cuddle, but is often blocked by his testy energy. The authentic feminine loves to cuddle and is supported by her esty energy. 

Another theory on why oxytocin release is harder in men than women has to do with how Cromagnum men and women procreated. In the early stages of evolution, men and women didn't have monogamous relationships. When a man was horny, he pretty much took whichever woman he wanted... the feeling of indifference and fatigue he felt after raping her, allowed her to escape.

So, all in all... men are wired to do what they do after sex. Despite what it seems, it has nothing to do with how they feel about us, or how indifferent they are to our wants and desires. They actually can't help it. So knowing this... I think all women should try to be a little more understanding when their guys roll over and start to snore. Besides... if you let him take a little nap, he'll be all ready for round 2 when he wakes up, well-rested.

Oxytocin's affect on the brain is greatly dependent on its interactions with sex hormones such as estrogen, progesterone, testosterone and corticosterone. However, its effectiveness as a 'cuddle hormone' requires the presence of estrogen. This fact may partially explain some of the behavioral differences between the sexes when it comes to intimacy, the desire for cuddling, and even touch's role in the ability to achieve orgasm, since women's bodies produce vastly more estrogen than the male body. Oxytocin makes you feel close and connected and vulnerable. The effects of oxytocin are offset by testosterone, so a high-testosterone person doesn't bond from having sex which is why bad boys don't get attached!
