depends on the girl. you cant say anything about "girls" theres too many of them, more than 50% of the population. fi you're talking about 15-25, thats still too many people to say anything about them all.
depends (like already sayd) on their self esteem. there are lots of ugly girls who dress nasty whore like, and act liek they are really hot, while they are really not. i know a very cute and rather attractive girl, who thinks she not pretty at all, and beleives no guy would ever want to date her. i have very good reasons nott to ask her out but i wish those reasons didnt exist almost everyday, because i would really like to.
