You’ve just had incredible sex with your partner, and all you want to do is initiate a quality snuggle-session and chat about what’s been on your mind lately.
But you turn over and someone’s out like a light. The AUDACITY. You’re annoyed and mildly offended — why is your man always dozing off post-intercourse?
It’s all in your head
There are a few reasons that men are prone to falling asleep after sex — and none of them have to do with your personality or performance in the bedroom.
The most fundamental cause of a drowsy partner is biology. According to Live Science, looking at the biochemistry of the orgasm reveals that during male ejaculation a cocktail of brain chemicals are released — and one of these hormones is called prolactin. While prolactin is linked to feelings of sexual satisfaction and the refractory period in men, it’s also a hormone that is present in higher levels during sleep.
Because prolactin and sleep are strongly linked to one another — and because intercourse orgasms release four times more prolactin than masturbatory orgasms — men are prone to being a lot more tired after a session between the sheets.
In addition to prolactin, oxytocin and vasopressin are also released during the male orgasm. These chemicals typically are accompanied by melatonin, the body-clock regulating hormone. The three of these hormones combined lead to relaxation and sleepiness.
Moreover, according to a study done by evolutionary psychologists at the University of Michigan and Albright College in Pennsylvania, the tendency to fall asleep after sex is actually associated with greater partner desire for bonding and affection. Yes, you read that correctly.
“The more one’s partner was likely to fall asleep after sex, the stronger the desire for bonding,” explains Daniel Kruger, research fellow at the University of Michigan, and lead author of the study.
The simpler explanation behind recurring post-sex slumber
If all this hormone and evolutionary bonding talk has got your brain in knots, there’s a more basic reason your man is sleeping like a log following intercourse. Sex typically takes place in the bedroom, and often in the evening. Our brains associate the bedroom with bedtime and it’s only natural to feel sleepy when put in this setting. Women can likely attest to tiredness post-intercourse, as well.
Feeling physically and emotionally spent after sex is very common, and even more so for men. Though you can’t necessarily outsmart biology (men are going to release those sleep-inducing hormones after sex no matter what you do), you can adjust environmental factors so that it’s more likely you can engage in a bit of post-coital conversation.
Men’s Health sleep advisor W. Christopher Winter, M.D. suggests keeping the lights on and picking a sex pose that’s not horizontal to keep your partner’s body perked up and alert after the act. Sure, this might sound risqué but variety is the spice of life — and surely mixing things up is better than listening to a symphony of snores immediately following orgasm.
