It seems unfathomable to me but they seem to be happy enough so whatever works for them I guess.
Me too, but, I'm not exactly "conservative" when it comes to intimate relationships, but I used to be. I was a virgin when I married at age 20, but when I was raising my sons I knew they might not take that same path, and we taught them to be responsible for their actions. My sons are married now, but I know they were not virgins when they married.
Diffn't strokes for difrn't folks, I suppose.
