It depends on the person. I've met skinny women who didn't interest me in the least, and I've met overweight women whose beauty haunted my dreams. The best advice I can give any woman is to take care of yourself and try to be the very best version of yourself you can be.
You're running about average there. Most women are a size 10-16. So, since the majority of women are in that range and they obviously are getting boyfriends, I'd say guys don't have too big of an issue with it.
