As someone who is also gay and overweight, I do not share your same point of view. After high school, I rarely if ever got teased about my weight. I’ve learned to accept myself and make an effort to take the time to portray myself in a way which I’m happy with myself. When people tease you, most of the time it’s projection. Either they have been fat, think that they are currently fat, and/or are terrified of becoming fat. Don’t take things so personal.
