I was an "ugly duckling" until I was like 18 so I can confirm you do get treated differently. It has it's pros and cons. You get ahead a little easier. Many people will help you out or let you off the hook for things just because of the way you look.

When I was single, I successfully seduced everyone I desired, and that was a huge confidence boost after being mostly ignored in the past. However, I couldn't always get them to have feelings for me, so I would often end up feeling very used in the end. I found that it's nearly impossible to have close friends of the opposite sex, which fucking sucks. I'll think I have this great friendship with someone only to find out that they're "in love" with me. Which they aren't, they just want to smash. I even try to make myself look like a hot mess on purpose when I go to work, specifically to keep the men from thinking of me in any type of way .

As another commenter mentioned, girls can be fucking cruel too. I've been bullied or ostracized a lot. I'm pretty thin/fit and have noticed that women who are overweight will treat me like shit more often than other thin/fit people do. It doesn't help that I'm extremely passive and non-confrontational.

Overall, I'm not going to complain. I've been dealt a shitty hand in many areas of my life so I will gladly accept being fortunate in my physical appearance.
