1. Thongs was original meant to be a type of bathing suit, like "Super high-legs".
2. Women wear thongs because they are comfortable to wear like men wear boxers or briefs. Men briefs are the same as bras and supports and help delay gravity.
3. She is fricken engaged. Game over. She is not five years old, and she is not
even 11. The guy has seen her naked, at some point, and to him, he could careless.
4. If their was a medical reason to switch to panties, briefs, or other lesser-garmets then you need to provide a medical reason. Scare her bad into panties.
5. About sluts. Sluts are only a ficitonal thing. Most "bad-girls" are never really bad to being with. Like when I was in highschool their was a girl who was the "self-proclaimed bitch" but nobody knew her name or cared about her, but me. Years later she is an accountant ( gold digger ) and has boyfreind who .....has lots of gold.
Another woman I knew wented on to become a playboy model. That is what she is doing now.
Another one was a model, and she had high grades in highschool, and was not super skinny.......
They are only acting. All women are sluts at one point in their lives. Just like all men are pigs who search the earth, search the sea, and search the sky for these sluts.
Your daughter could walk around in a string bekini and people would be staring because it is a string bikini.
