I really don't like it sticking out the top of jeans or w/e. It doesn't turn me on. What does turn me on is getting a chance to peek at her undies when she sits in a short skirt. Now that's what I call getting turn on. Lol! Maybe because I think sometimes girls don't realize it shows some times, and some times they do know but let it be. But to purposely open their legs wider than what's modest I wouldn't like. It's just sexy as heck when a girl crosses her legs or sits down and suddenly you get a peek at her very colorful undies cause he skirt is so short, especially those stringy hemmed jean ones that are soo hott!
It can be incredible sexy to some guys. To others, it may not.
Personally, I take a look or two but what runs through my mind is "what a slut" even if the girl isn't. I like classy and I've asked my girlfriend and my female friends to pull their pants on occasion.
It does draw a lot of attention and a lot of guys will like it because it is revealing but still leaves a little mystery to the mind.
