|Why not, right?|
"So if the guy doesn't care - why bother?"
"But if there is no guy to impress - why go to the trouble?"
...Are the questions most women normally ask.
My answer? Self-esteem begins and ends with you doing things for you. If it makes you feel good to wear lacy underwear and a matching bra - do it. If wearing a thong makes you feel more sexy - go for it.
The thing is - the more sexy and beautiful you feel, the more confident you'll be. The more confident you are, the more comfortable and at ease you'll be. If your goal is to find a guy to admire that lacy thong, this is the first step. What guy wouldn't want to be around a confident, comfortable woman?
Only one that isn't worth your time in the first place.
