There is an abstract of one study which evaluated blood pressure and electrocardiographic changes with ejaculation. The results showed an increase in blood pressure and EKG changes suggestive of cardiac stimulation. The release of epinephrine and the body’s response to it can make one feel tired. While some can be satisfied with a spiritual explanation of this phenomenon, I’d rather see something scientific.I think I’ve provided a fair amount of physiology to support my side. You have the responses to one poorly worded question on an Internet questionnaire and 12 guys who claim they don’t masturbate (no answer yet regarding if they had sex after PE). So your explanation is also "just your opinion."
I thought you and gprent agreed to disagree. Can’t we also have that arrangement?
Oh man, I thought it was just common sense for everyone that cumming drains you. I don’t even want to give an analogy because it would be redundant.
Westla, the image of the unsatisfied woman whose lover ejaculates, grunts, and collapses on top of her is so common that it has become a cultural joke, but the exhaustion that men feel after ejaculating is as old as the first coital groan. I used to box and all of my trainers told me never to ejaculate at least 2 weeks before the fight. They were right, I had much more stamina by following their advice. But its not just athletes that have known the weakness and lethargy that follows ejaculation, artist have also felt the lingering effects on their work. Jazz musician Miles Davis explained in an interview in Playboy:
Davis: You cant cum, the fight or play. You cant do it. When I get ready to cum, I cum. But I do not cum and play.
Playboy: Explain in laymen terms.
Davis: Ask Muhammad Ali. If he cums, he cant fight 2 minutes. Shit, he couldn’t even whip me.
Playboy: Would you fight Muhammad Ali under those conditions, to prove your point?
Davis: Your goddamn right I’d fight him. But he’s got to promise to fuck first. If he ain’t going to fuck, I ain’t going to fight. You give up all of your energy when you cum. I mean, you give all of it! So, if you’re going to fuck before a gig, how are you going to give something when its time to hit?
So anyways westla, if your saying you personally don’t feel any loss of energy or feelings of lethargy after you cum then you must be superhuman. As for most people though I got to believe that they don’t really need a study to know they have a energy loss of some sort when they cum. But yes lets agree to disagree, I’m not arguing here. Take care
