He was mature for his years. His kink was that he wanted to fuck a mature white married woman. He was actually respectful of me. When my wife took him into our bedroom, he told her he was concerned about what I would think (he knew I was aware that he was invited over to our house). She assured him I had no problem with him fucking her and indeed would like it that he did.Taking what she was saying. The issue doesn’t seem to be in just his younger age but that he was also emotionally immature. I don’t think a lot of women want to be fucking with younger guys that act like bratty kids.
Sounds more like your wife was dealing with a younger guy who behaved more like an adult.
I know I am totally turned off by women of any age using baby talk during sex. Something about hearing a grown woman saying “pee-pee” for a penis is super cringe worthy. I’ve heard that in a few roleplay POV porns and it’s a big no-no for me. It sounds like she’s talking to a child.
