I keep bumping into comments from women online like "my husband is too busy watching porn to have sex with me."

I don't understand this mindset at all. I would much rather fuck a real live female than my hand. If i could, i would exclusively cum in the holes of a woman. So a man being too busy with porn to fuck doesn't compute.

Is this just a case of most of these women being obese?

Has anyone ever encountered this scenario in one of their relationships or heard of it happening in a friends relationship? Do you think this phenomenon is common?
