We've gone over this before, probably more than once.
Men who are inadequate at intercourse, for any number of reasons, too small, cum too fast, lack of skills, or other reasons, only create frustration which soon turns to resentment for the women. When the woman finds and experiences a superior lover, it's easy to understand why she doesn't want inferior sex anymore from her husband. I'm cut off from sex and receive hand jobs only for the first two reasons I listed above, and agree it's the right thing for my wife to do.
It’s really funny that women are not held to the same standard when it comes to intercourse. If you have a vagina and can move - your good from a physical level.
Men have tons of things they need to be able to do. Gotta be big, have skill, fuck for hours, make her feel things she’s never felt, fuck me hard but be gentle and loving. If you can do these things, you might be able to fuck my pussy tonight....but I just want to let you know, “I am looking for something and someone better”. DAMN.
Men are like my dick is always available for any vagina. We will enjoy.
