As a dude, pouty lips aren't really interesting to me. I can't speak for broad demographics but "Dick-suckin' lips" or "the pouty mouth" or whatever term you care to use are talked about by women FAR more than men.
That being said, we don't talk about lipstick EITHER but I can't deny it works better than not having it, so who knows? Maybe it's the SECRET TRICK that will suddenly make you pretty (for whatever that means) but my money is on it being another thing women convinced themselves was important when it wasn't.
The key to remember is that you should NEVER do bad things to yourself (injections, topical irritants, whatever) just to try and make your lips bigger and freakier. It's a turn-off for some, it's a mostly-unmentioned turn on (dudes don't talk about your lips in the locker room, unless they're talking about getting 'em wrapped around their dicks) if it's a turn-on at all, and if you're going to alter yourself by modifying your appearance, you might as well meddle with the things we DO talk about; your breasts, butt, and hair color.
But if you have naturally full lips, don't worry about it. The worst it might do is make a few other women irrationally jealous, and you can't stop crazy folks from bein' crazy.
I have always hated my thin top lip... but I've been using Liptful... and its seriously amazing! Handmade, hand-painted, and made from all natural clay. And they have tons of shapes and colors! I've tried all of these things and they last for a little bit, but with this little tool I can plump before I go out, and then go to the bathroom after an hour or hour and a half, and plump while I'm "using the restroom" and go back out with full lips again!! know more here about best lip plumpers: http://bit.ly/1BU0VFa
I've been using this lip gloss for a few years. When you first put it on, it stings a little, but it makes your lips full, and pouty. :) Lip stick always makes it looks fuller, and lip gloss! http://tinyurl.com/6n95erm
Angelina Jolie doesn't really have pouty lips. She just has big lips. I've been told by everyone that I have pouty lips. It just means you have kissable lips, attractive and cute lips. It means your lips are full. It's a good thing, trust me. :)
