I understand it, sure,there is 2 big things that I think people would need to understand here
First, sex is 50% mental and 50% physical, and I would even say for some people is more mental than physical. With that in mind the pleasure you feel with your dick in a womans pussy is not he entire reason why you enjoy sex, and as somebody say before if you have learned how to jerk yourself off very good, the pleasure you will feel jerking off will be almost the same as what you will feel with a pussy... IM ONLY TALKING ON A PHYSICAL LEVEL HERE not talking about the entire experience
The other half of the pleasure you feel in sex is basically the pleaure of the mind, the pleasure of being a man FUCKING a woman, submitting a woman with your dick and hearing her moaning because of what a big macho you are.... that feels good right? well thats the other part of why you enjoy sex ON A MENTAL LEVEL, and because of millions of years of evolution that plesure multiplies when you get to fuck a "new" woman, when you get to submit another woman with your dick because that makes you feel more of a man and because thru evolution thats how you make sure the species continues by fucking women
and here comes the second part of the explanation... and this is something that only married men can understand... no sorry having a long relationship doesnt count, oh you lived with your girl for 3 months? nope sorry it doesnt count.... only if youve lived with a woman for years together, sleep together, use the same bathroom, see how she wakes up, pass her the tampax when she forgets, cleaning the garbage that you both used, smell her bad breath after you both ate, hearing her farting in the bathroom or in the next room... only if you have lived thru this, not once or twice but year after year, only then you will undertstand that no matter how dolled up and pretty your wife looks when you guys go out,the way you look at her will never be the same way that another man will look at her, YOU WILL NEVER AGAIN see your wife with the same eyes that you were able to see her before you experienced all those things that I just listed... and thats when the "mental" part of the sex comes into play
I have to leave now and I dont want to erase this whole damn thing, if you are smart enough I think you understand how these 2 big ideas merge together... basically when you jerk off you are tricking your mind into feeling pleasure in fucking a new woman EVERY TIME and because of the reasons I explaned THAT could be more pleasure than fucking a woman who you have seen at her worst instead of a woman in the video that you have never seen at her worse, you completely use more of the mental pleasure of sex than the physical part, and if you are good at trickin you mind voilaaa you will feel more pleasure in masturbating than fucking your wife.
As I said at the beggining I understand the logic but I also see how it could be destructive and how you must not try to replace the physical experience of connecting with your wife with something created in your mind... I dont agree with it, but as I said I "understand" the logic... feel free to criticize or say Im wrong, Im not trying to say anybody is right or wrong here, Im just sharing how I came to understand why married men get to this point, peace!
