One time I wore a thong to school and ended up getting suspended.
What made you wear a woman's thong to school?
It was part of a bet.
It sounds like you are very adventurous, but you should respect the dress code of your school at all times. Next time someone offers to make a bet like that, just refuse to take part.
I want to try it again, but this time I think I'll just wear girl's panties.
As long as you are following the dress code of your school you should feel free to experiment within those confines. Just know that people may tease you if they find out and it'll make things hard. But at the end of the day, you should be yourself.
