I think it varies. I think Islamic and African societies aren't looks obsessed. Islamic society is very desexualized and women have to cover up. Latin societies are worse when it comes to looks-obsession and sexualization of girls.
HC, this is horrible news. I feel very bad for you. I don't know what to tell you, other than to foster gratitude because it could be a lot worse. When I was auditioning for a club, I worried about my looks, so I put it in perspective by comparing myself to women in wheelchairs and 80 year old women and obese women who don't stand a chance. It made me feel more at ease and I was able to land a gig and now I like my body.
It would be helpful to see what you look like to see if makeup would do the trick. But that's no excuse for people making mean and hurtful comments. Makeup is for you to feel good about yourself and get into touch with your feminie side. It's not to attract guys.
You've internalized the idea that you're unattractive. How do you know? Different guys have different tastes.
