They don't get uncomfortable. You put them on for the first time, you're like geesh this is kinda uncomfortable, and then you just get used to it. Thongs are nice because they don't give you disgusting underwear lines.
1. They don't feel uncomfortable (to me anyways), and I don't carry around an extra pair to change into..
3. Change up into a new one everyday..I don't sleep with them on.
4. I'd wear a thong anywhere..Its not like you see them anyways, unless a girl wants you too. - I love them, they're pretty comfortable for me. I don't wear them everywhere but do own more thongs then bootyshorts or anything else.
