I used to turn heads when I was younger. There are definitely some advantages. You get better customer service, people are more likely to offer to carry things for you, hold doors open and go out of their way to help resolve minor issues. People smile at you.
The downsides massively outweigh the advantages though in my opinion.
From when I was around 12 or 13 men would harass me and grope me in the street. I had male Teachers, neighbours and friends Dad's make inappropriate comments about my looks as a teenager. I became very anxious in social situations.
Many men who have seemed harmless have rapidly become nasty and aggressive when I've turned them down. I've been inappropriately touched by university lecturers, a driving instructor, then work colleagues and more strangers than I can count. Public transport still fills me with dread due to so many awful experiences with men, and unwanted male attention has ruined many nights out. Men I dated would become jealous and obsessive and would harass me (and in one case my family and friends) when I ended things.Twice in my life I've had men who I genuinely believed were among my closest friends, men who I'd known for years and loved like brothers, make unwanted sexual advances towards me. On both occasions they waited until a vulnerable time (the first immediately following a breakup, the second a bereavement) to make their move which was incredibly hurtful.
At work you can never be sure if people value you for your ability, your ideas and your experience or if you're getting special treatment because of how you look. People also tend to underestimate your intelligence and women are suspicious of you.
I've had friends get annoyed with me because their horrible lecherous boyfriends or husbands have flirted with me in front of them, despite me being clearly mortified. You can never admit to even the slightest insecurity or self doubt because if you do it will be met with eye rolling and sarcasm rather than empathy. There's an assumption that because of the way you look life must be easy and perfect.
My DD is always being told by adults how beautiful she is. She is only 10 but I worry for her.
