This is soo embarring!! Advice?

Relax kiddo it will be fine :). Thongs are JUST underwear and they are y and comfortable. In a few years, you will be wearing them yourself no doubt. It's not just a ual thing anymore, it has become a regular part of our society, back in high school and college, (2006-2011) it was weird when we DIDN'T see a girl in a thong. So it's really nothing to freak out about. The best advice I can give you is talk to your mom about it.
