Why? What makes it yukky? Is it some sense of shame of your body? Why is that? What if your mom said something like your dad is jealous of your cute figure cause he doesn’t have one? I’ve actually heard women remark of other women/girls figures and that seems ok. Why isn’t that yukky?
I think the thing required for a girl to not be bothered with such remarks is to have grown up understanding and being a part of the type of teasing boys do. For a girl to just walk into that with little previous exposure would be a problem. But that has a lot to do with their social conditioning, which comes back to both the father and the mother.
OK, I don’t know what my wife and daughters say in private. But I do hear them around the house. If they are having one kind of talk between them and another kind around me, then there is a problem, IMO.
