I have not had this specific experience, but it does not surprise me that it exists. And given that men are taught to repress / deny what they feel, it is no surprise that it is late being discovered.

While "dopamine rebound effect" is a hypothesis, I think it's more likely to do with all the hopes / dreams / aspirations that go into sex, only to find it's not that satisfying after all, particularly if your partner wasn't that into it. It's like the post-Christmas letdown that tends to fill the offices of head doctors after the first of the year.

Some of the replies here are talking about something longer-lasting than just the immediate post-coitus time frame -- spilling into the next day.

You could set your clock by the fact that sometime in the 48 hours post-coitus (or really post anything intimate, like a good romantic date night) my previous wife would pick some kind of fight over something she observed that proved to her I didn't really care / love her. In her case it was pretty clearly abandonment issues. Her father abandoned her and her mother when she was 11, just snuck off without comment in the night and was never heard from again (eventually traced to Alaska, about as far away as one could get without leaving the country). Every time there was good intimacy with a man, she would pull away from it because she couldn't trust it. And she was searching for signs of abandonment, which she probably was doing ever since her Dad surprised her by leaving. Despite that I stayed strong with her through a terrible illness, this sense that I might abandon her at any moment never really left her. It's a sad commentary on what lasting harm a parent can do to a child. And yet her father wasn't much of a throat to choke, by all indications he was just a victim of PTSD, courtesy of the Korean war. He died alone of COPD somewhere out in the tundra, so I guess life "punished" him sufficiently.

Amazing how life can sometimes transform even the transcendent into a source of suffering ...

I want a sandwich.

I hate myself to no end for not being able to keep up with this kinky, rough goth chick last month. Don't know if that's similar?

Reminds me of the words of Neil Diamond’s song” You don’t bring me Flowers”........”After loving me late at night.....you just reach over and turn out the light”! it is sad. If you don’t lie in each other’s arms afterwards it can often feel like a rejection and can seem almost like an abandonment to many after such an intimate act. I know many women feel this and so it is not entirely surprising that men can have these feelings too.

Guess I'm 59%

Where's my cigarettes?

Can't relate to that, my feelings are a mix of euphoria, comfort, natural high, warmness, cuddliness. All pretty positive things really!

Totally alien to me, but then i am a cuddler after sex. ?

These guys are either doing it wrong or having sex with the wrong women

yes, communication is a great aid towards understanding & emphasizing with the other - always.
