Why Do Some Women Insist On Not Wearing Underwear? Especially With Short Shorts? Could They Be Advertising?

Sometimes its just more comfortable to go without. I think a lot of females thinks it turns a guy on; they're not necessarily prostitutes, but some just want attention. The girl you know may be wearing a g-string (harder to tell than a thong).
I personally can't stand going commando...it kind of creeps me out. Lol.

I agree with those that feel it is very freeing and comfortable.  I think it definitely draws some attention to those men that are looking as they try to figure out if it is a G-string or nothing at all...both turn ons.  Women, if you haven't tried it, I strongly encourage it!

My sister says it feels freeing and less constricting when she doesn't wear any.  I also think it might be a way to get guys to notice them.  I agree that I can't stand not wearing any.

I am not wearing any knickers now, and I personally think its more comfortable this is the first day ive gone without and I will be doing it again.

I think they go without them so that their panty line doesn't show. Or the can wear a thong.

As a man I see nothing wrong with a Young lady not wearing underwear

Medically.... It's better for your vaginal health, going commando helps prevent yeast infections and sometimes UTI's... I only wear panties around that time of the month

It's comfortable and you don't have to worry about any irritation from underwear rubbing. I rarely wear underwear and it's not for attention or anything. I am however considerate and do wear underwear if I'm going shopping and know I'll possibly be trying on clothes.
