When every reasonable man understands that he can't satisfy his wife's sexual needs, he quickly finds a solution to fix it and save a marriage if it's important for him. It's a category where cuckolds let wives cheat on them and obediently watch skilled stallions fucking their holes. It isn't cheating because beloved spouses' sexual pleasure is the most important thing for hubbies. When a man really loves his wife, it isn't a problem to give her the green light to have sex with another guy in his presence.
