i have this weird babyface thing that makes me look younger than i am in my 30s (i get people thinking i'm 19-20is all the time), but when i was 13+, i grew my tits in and apparently that made me look 19-20 too. i had a lot of inappropriate attention from adult men, some who looked horrified to find out they'd been hitting on a teenager, others that seemed not to care and would try to offer to get me drunk. there are all types and it is not always easy to tell how old someone is without id.
