I looked at the pictures on your profile. You look normal, but not thin. There's nothing wrong with being "normal" as long as you're healthy. Ask your doctor what the right weight is for you and the correct body fat percentage too. Overall, I'd say you have nothing to worry about, but if you absolutely must know more, talk to your doctor. He's going to be the most qualified person to talk to.
It is more than ok it is so sexy!! I did my home work and checked out that size of jeans, including the ass haha and lets just say if you walked past me in a pair of tight size 10 jeans I would be checking you out and thinking good things about you. That is exactly the size I like so sexy. I mean this respectfully.
Girl did you really just ask that? I know tons of girls who would kill to.be that size and go to all kinds of extremes to get there. Your skinny as long as your healthy your good have confidence in yourself and embrace what.God gave you and def don't let people make you think you need to get any smaller
