I think when you're young, you're so fearless about this stuff.
I know that I was - I thought that I'd do my thing, then pop in and get whatever I wanted fixed with cosmetic surgery etc...
Then, before any of that happened (skint, obvs) I had kids. I had 2, and both by EMCS. I realised that there was no bloody way I was letting a doctor cut me up unless it was properly life-threatening - and distress or dissatisfaction with my body just wasn't going to be enough. Better to cover up than go through that again (and I had easy EMCSes - no problems with healing or anything)
I don't know what to do about it, because I do also strongly believe in body autonomy - and yet, these young, scared, yet brave (or possibly foolish) people are risking their lives, and I think, that hard as it is, it's probably still too easy.
