I don’t think I’d call it penis envy. I think it’s more that they don’t think it’s fair that their looks matter - to their disadvantage. As for the Hollywood loons - I think it’s going along with the crowd, they want to go with whatever seems popular.
Well...life isn’t fair.
But I had a really cute friend who grew up in an affluent family and married the same. She was always feeling sorry for those less fortunate - it seemed to be baked into her. Some sort of guilt for being lucky.
