How to get pouty lips?

seriously I see lots of girls online doing the pouting look and I wonder whats so attractive about it , like sure for girls it looks attractive and cute but honestly I don't think guys really like the pouting look , so I suggest you give a natural smile , because smiles are cute , pouts aren't so attractive ... And I can't pout because it seems like i'm naturally pouting sorta because my lips are big ... Well not big but as in natural small pout , but I don't like it because I think girls who smile are gorgeous because smiles can make someone look radiant and amazing :)
