My experience with an older dom was nothing like that. We had a 25 year age gap (20-45) but he knew exactly where the line between the sex life was and our real lives. I could talk to him just like a friend, if I needed something, he was there like a friend. We both valued each other greatly with no issues. The only reason we stopped is because I moved. I think that was just possibly his personality and his view towards younger women in general honestly.
