I had a breast reduction immediately after I turned 18. Yes, they hurt my back, but I also experienced significant psychological distress because of them. Not just did I garner very unwanted male attention, but I mainly felt fat and unattractive. Not "less feminine", though, mind you.
The surgery and recovery was rough, and trying to breastfeed my children (more than 10 years later) has been a struggle, but I'm still glad I did it because the surgery did make me feel a lot better and took a huge physical and psychological weight off me. I have scars that are visible, even more so when I'm intimate with someone, but they've never bothered me and I never felt the need for any additional cosmetic surgery, so in my case the choice was the absolutely right one, and helped me lead a healthy and normal life.
However, two things.
I don't think I was properly prepared for the longterm consequences. I dimly recall the surgeon mentioning something about potential difficulties if I ever wanted to breastfeed, and I also dimly recall both not really caring and not really understanding. I was considered gifted, an intelligent, well-read, and "very mature" young woman in my late teens, and I. Did. Not. Understand. The. Longterm. Consequences. I was simply too young, naive, and inexperienced to understand that I'd really want to breastfeed one day, and how exactly the surgery would make it difficult for me.
And secondly, I am indescribably glad that gender ideology wasn't around when I was growing up. I was a vulnerable, anxious teenager with depression and an eating disorder. I had several gay friends, and often wished I could be one of them - a gay boy rather than an awkward, gender-nonconforming nerdy girl with huge boobs.
Fortunately I grew up, went travelling, moved to a city where I met people with whom I actually connected and felt comfortable, and am now a happy slightly gender-nonconforming woman married to a happy slightly gender-nonconforming man.
I am worried for our children, though. Gender ideology is slowly seeping in where we live, and of course it's everywhere online. Fortunately our children are attending a more conservative school, so I hope they'll be protected there at least as long as they're small. But I can't say that I don't have a bit of a stomach ache thinking of their future.
