Have you ever been lying next to your male partner or lover post-sex, watching them snooze away as if it\u2019s the best sleep they\u2019ve ever had? Not much time for <\/span>pillow talk<\/span><\/a> or cuddles, not interested in eating, watching TV, or anything else?<\/span><\/p>\n

Yeah, it seems quite rude, doesn\u2019t it? Well, the good news is, they\u2019re not actually trying to be disrespectful, and no, they aren\u2019t bored with you either.\u00a0<\/span><\/p>\n

There\u2019s actually a solid, biological reason why men are tired after sex. So, what is it? Why do guys fall asleep after they come? The hormone, prolactin.<\/span><\/p>\n

What Is Prolactin, the Chemical Released After Sex?<\/span><\/h2>\n

Prolactin is a hormone that\u2019s produced by the pituitary gland, and has many functions.\u00a0<\/span><\/p>\n

One particular case includes the fact that this chemical is released after sex, and plays a role in a man\u2019s refractory period (the time before the next <\/span>erection<\/span><\/a> is possible).\u00a0<\/span><\/p>\n

Prolactin surges after orgasm, and creates feelings of sleepiness, reduced <\/span>sexual arousal<\/span><\/a>, and relaxation. The perfect recipe for what? Sleep!<\/span><\/p>\n

But then, why don\u2019t men fall asleep immediately after <\/span>masturbating<\/span><\/a>? Well, interestingly, post-coital orgasms release four times more prolactin in men than when they masturbate.\u00a0<\/span><\/p>\n

But is prolactin the only hormone that causes men to feel tired after sex? Actually, no,<\/span><\/p>\n

Why do Guys Fall Asleep After They Come? A Cocktail of Hormones!<\/span><\/h2>\n

While prolactin plays a big role in sleepiness after sex in men, there are too a slew of other chemicals released after sex that contribute to sleep.<\/span><\/p>\n

After ejaculation, a man\u2019s dopamine (the \u2018feel-good\u2019 hormone) levels drop. Dopamine is a stimulating neurotransmitter that makes you feel awake, so when this hormone drops, the opposite effect takes place.<\/span><\/p>\n

Then, <\/span>oxytocin<\/span><\/a> and vasopressin (the \u2018bonding\u2019 hormones) rise. Oxytocin can help reduce feelings of stress and induce a feeling of safety, making it easier to relax, and vasopressin is linked to a calming effect as the heart rate slows down, there\u2019s reduced alertness, and the body shifts towards rest and recovery.\u00a0<\/span><\/p>\n

Additionally, serotonin levels increase, which can make the brain feel \u201cready for rest\u201d.<\/span><\/p>\n

These hormones, along with prolactin, and if you\u2019re having sex at night, with the lights off, in bed etc, a sense of calm and drowsiness is experienced. One\u2019s body clock then signifies that it\u2019s time for bed, and further releases melatonin, a hormone that ignites your sleep cycle.<\/span><\/p>\n

Why Don\u2019t Women Fall Asleep, Like Men Do, After Sex?<\/span><\/h2>\n

The next question you may have is, why don\u2019t women fall asleep after sex? Well, more like; why don\u2019t they pass out like men post coitus? Surely men and women experience the same amount of hormonal surges and drops? Actually, no.<\/span><\/p>\n

Women don\u2019t experience the same prolactin surge as men do after orgasm. In fact, way less prolactin is released after climax in women. Additionally, while they do release oxytocin, it more so evokes feelings of bonding and stimulation as opposed to the sedation effect that many men experience.<\/span><\/p>\n

Another reason why women don\u2019t fall asleep straight after sex like men is because they don\u2019t have a strict refractory period. Women can continue to be aroused, and they can experience <\/span>multiple orgasms<\/span><\/a> in succession without needing to rest.<\/span><\/p>\n

Then, there\u2019s the element of neuroscience, aka\u2026 the brain. There have been brain imaging studies using technologies such as an fMRI scan and a PET scan to measure what part of the brain lights up during sex and orgasm. It was found that, after climax, a man\u2019s brain often showed decreased activity in parts related to attention and arousal, resulting in feelings of relaxation and sleepiness. A woman\u2019s brain often maintained or even increased activity in these regions after climax, suggesting alertness or cognitive engagement.<\/span><\/p>\n

From an evolutionary standpoint, women\u2019s bodies may be more in-tune after sex for purposes such as nurturing, bonding, and caregiving roles (from the release of oxytocin), and there may be emotional and relational reasons that could keep women more mentally engaged after sex. On the other hand, men\u2019s brain patterns favour energy conservation and recovery after ejaculation.<\/span><\/p>\n

Post-Sex Behaviours<\/span><\/h2>\n

By now, it\u2019s evident that both men and women have different post-sex behaviours. And when one partner partakes in one particular kind of behaviour that bothers another, such as falling asleep, it\u2019s almost expected to feel vulnerable.\u00a0<\/span><\/p>\n

But did you know that, according to a <\/span>pair of studies<\/span><\/a>, if you\u2019re happy with what happens post-sex, you\u2019re more likely to feel satisfied with the sex itself, as well as your romantic relationship in general?<\/span><\/p>\n

In that regard, it may be a great idea to start focusing on the time post-sex, rather than just the sex itself.\u00a0<\/span><\/p>\n

This is because \u201c<\/span>we are in one of our most vulnerable emotional and physical states when we are sexual with another person, especially when there are strong feelings with that person,<\/span><\/i>\u201d says sex therapist Ashley Grinonneau-Denton. \u201c<\/span>The time after sex is a critical opportunity to build intimate bonds, not emotional walls.\u201d<\/span><\/i><\/p>\n

And according to sex therapist Rachel Needle, <\/span>\u201cGiven the research, couples should make an effort to connect post-sex. The time you spend post-sex can increase intimacy and bonding, as well as commitment, sexual and relationship satisfaction.\u201d<\/span><\/i><\/p>\n

Sex therapist Emily Jamea has one suggestion that may help in this regard. She says that, if one partner is inclined to fall asleep after sex, they should turn towards their partner, not away.<\/span><\/p>\n

\u201cSometimes just rolling toward (as opposed to over) and sweetly telling your partner how much you care about them while holding them in a spooning position can be just enough to make them feel connected<\/span><\/i>.\u201d<\/span><\/p>\n

How To Not Take It Personally When a Man Falls Asleep After Sex<\/span><\/h2>\n

Having said all of this, it\u2019s still possible that a partner may take it personally when someone they\u2019re intimate with falls asleep immediately after sex.\u00a0<\/span><\/p>\n

So here are a few tips to remind you that it\u2019s almost never personal:<\/b><\/p>\n
