why are men so tired after sex? TMI alert

My SO eats well, is slightly overweight, a social drinker, doesn’t use drugs and we both work out about 4 times a week. He hasn’t had a checkup in a couple of years, but his last one was just fine. And he managed a big FIVE yesterday! Makes me wonder how he’ll keep up when I reach my (supposed) sexual peak at 40!

ShibbOleth, I went looking for more info on prolactin and found this very interesting article: http://news.bbc.co.uk/1/hi/health/1949087.stm
I found it interesting because I’d thought that prolactin and oxytocin were strictly female things but have discovered that they aren’t. TMI ALERT–there are two bare breasted pics of a woman in a delivery room and a woman nursing on the page I cited. Just thought you might want to know if you’re doing your viewing at work.

Don’t forget that women also have testosterone as well. We are not so different, you and I?

I am almost certain this is completely false. It’s been a long time since I read it but I believe scientists measured (not sure how) physiological reactions in men and women during orgasm and women were found to have what would seem to be more powerful (and longer lasting) orgasms.

It’s so the female can make an easy kill after mating.

Oh wait no. That’s mantises (mantisi?)

What time of day are you having sex? During the week, after getting up at 06:00, working a full day, going to the gym or doing whatever else I do after work, and then having to exert myself during sex at 22:00 - there’s no way I’m not going to fall asleep afterwards.

I’m a morning person - I can’t understand why more people aren’t. The sex is better.

Time of day doesn’t seem to matter. And he’s not falling asleep, but it takes him a lot longer to recover than it does me. As for yesterday’s experiment, it was five times total scattered throughout the day from about 8a.m. till about 8p.m.–lots of rest breaks in between.

It’s because the woman has stolen your natural fluid essence.
Fluoridation of water also does the same thing.

Now feed me the ammo!

Or to allow the female to escape.

I think the reverse is actually true

This is what I’ve always guessed. After sex, the male, having done his part (biologically speaking), is now unnecessary. Should a predator come along at that moment, the sleepy male becomes an easy target, allowing the female to run away.

:eek:

5 times!!!

Say no more – your man is likely within the top .05 percentile among men his age if he can manage 5 a day. You are a very, very lucky woman.

Are you sure he isn’t a triathlete on the side? Or Viagra enhanced?

See Who gets the most pleasure from sex, the man or the woman? I quote:

The article goes on to discuss multiple orgasms and status orgasmus, which tip the scales in the females’ favor. But, neglecting that, it sounds like an individual male orgasm is just about identical to an individual female orgasm.

I am not particularly tired after some vigorous sex. There have been a few times that my wife have had such a great time it made her go to sleep (I swear it was after not during) I would mention it takes me a bit of time to be “ready” to mambo. I think the sleepiness is induced by the endorphines released during orgasm not so much for the actual physical exertion. Both of us do feel real relaxed afterwards.

When a man ejaculates, his testosterone levels plumit. It may seem counter inuitive, but is also the primary reason for the refractory period (when you can’t get it up after sex). This also may play into effect with the tiredness, especially of older men who have less testosterone. If he doesn’t have the desire, and youre oth lying in bed, then the natural thing to do is fall asleep. On top of this, The actual act of ejaculation is brought upon the sympathetic nervous system, which is also involved with being tired, fo instance after one eats a large meal. This too probably has something to do with it. As to men having better orgasms, the male and female orgasms are almost identical when it comes to your nervous system. This, plus the fact that the cliterous has twice the number of nerve endings as the penis, but is quite noticably smaller than a penis (I should hope so). It may be a psychological problem too. If you have sex in bed, which is often associated with being tired and sleepy, then when you’re finished, it’s your mind’s cue telling your body it’s nap time. Thus, another way to decrease tiredness is to have sex in a place where he is often active and energized, say a study, or your local gym (get permission first).

count me as the opposite of the OP, i’m shattered, irishfella isn’t.

but i’m
a)multi orgasmic
b)lazy.

My 32 year old husband pulls me in to cuddle and drops deeply asleep, day or night. Sometimes I feel alone and abandoned but mostly I take the opportunity to tweeze his eyebrows.

It’s not the loss of vital essence. We’re just tired out from all that foreplay.

I’m a twenty-six year old male, and I frequently doze after an orgasm. The reason is simple, I need sleep. I am chronically sleep-deprived, and when relaxed, as in the afterglow stage, I doze off. If I’ve jhust woke-up or have another reason my body isn’t tired, I feel energized by the exercise. So the short answer is:
Orgasm=relaxation=nap.

Your SO probably needs the sleep if (s)he dozes off, (s)he may have a sleep disorder, or just need to sleep more than (s)he used to, and not realize it. Let your SO get a nap before sex, or an extra hour or two the preceding night, and see if (s)he is still sleepy, after orgasm.

I think that’s purity of essence.

“…and I was feeding you Jack, you said feed me, and I was feeding you, Jack…”

In my case it usually has to do with how emotionally stressful my day has been. If it’s been a good day my recovery time is mch shorter.

No, bordelond, he’s not a triathlete and he’s not on viagra. He claims that he’s making up for years of going without. And thompson, we’ve done it in the living room and the bathroom, but haven’t thought to try the gym. Now you have me thinking of Nautilus equipment in a whole new light!
