I've had some form of this. Nothing extreme. It's been a very mild feeling. It's probably just coming back down to "reality". You have all that feeling and endorphins running through your body and then after the climax, there's only one place to go, and that's down. You kind of feel "dirty". Even after masturbation. I haven't felt that way in a long time though, and it's not every time you have sex either. I don't know why.

...and as someone alluded to, I don't think it has anything to do with the partner or how you feel about them. It's a totally different feeling. I have felt both lol

I have had sex with women I didn't want to "bond" with, and I felt fine after having sex.

It's also nothing to do with religion for me. I have never been religious. Never read the bible. Never gave a shit about the limitations people have wanted to put on other people as a whole when it comes to what they want because of their religion.

Probably from knowing that is the moment that is farthest from the next sexual encounter

92% Get Sleepy after Sex, the other 8% fall asleep while think about round two!

In French, orgasm is called la petite mort (the small/little death)... probably comes from somewhere.

That seems like a rather sad statistic. I'd be curious what percentage of women feel the same, and is it possible this is really more indicative of how many aren't with partners with whom they truly, deeply, connect on every level?

I never felt sadness or irritability after sex..........if memory serves

To me, sex is more mental than physical. I love to cuddle to sleep after sex. Never felt any such sadness bullshit however.

I sometimes experience great sadness after orgasm (even with a partner). This has nothing to do with how bonded I feel with my partner.

When sex is good (and it often is), I feel more alive than I can imagine feeling at normal times. Full, like a brand-new car with a full tank of gas. It's like I can feel every tendril of my nervous system like a glowing tree inside my body. Strong, like steel, the surface tension stretching my skin. And I see colors, deep rich colors like amber turning into red, then purple, then glowing white-hot as if the colors themselves are on fire.

And just so, just when I am able to palpably feel what it is to be divine-then it is gone. It is a time of extreme vulnerability for me, and often sadness rushes in to fill the void, and brings me to tears.

And this, THIS, is what I have always needed my lovers to understand-that joy and sorrow, anger and love are mixed together forever in an intractable knot in my heart. Some have, some haven't.

It makes sense from a psychological viewpoint, after the high comes a low.
