I love thongs. They are suprisingly comfortable and I think they are kind of fun to wear (more fun than my "granny panties"
Kate you are right nice underwear can make you feel nice. When I was still on the dating scene I always made sure I had on matching undies and bra. Not because I was planning on anyone seeing them (but me), but because they made me feel special, confidant, and like I was in control. Honestly, I can't explain why it made me feel that way. But, it did.
On that note I have to add, it is important that you wear pants that hide the fact that you are wearing a thong...that thong hanging out above the waistband thing...I am not a fan of that.
