Tbh, I think I look OK. I actually think I have quite a nice body. I mean, Victoria's Secret is never going to banging my door down... but i think I'm ageing pretty well and I (used to) feel fairly confident.
I'm not sure about the confidence being attractive thing either. When I was at most confident - size 10/12 (not a perfect figure by any means but quite slim), happy to walk around naked, dressed attractively, walked confidently etc was when I attracted the most criticism.
A lot of men seemed put out that I wasn't more self deprecating and had the audacity to think I was ok as I was. And this wasn't just men I was dating. Random men I encountered seemed to think it necessary/appropriate/required to put me in my place too. Sometimes, they focused on a specific aspect of my body, sometimes it was a general 'fat' comment.
(I can't imagine any of those men being so 'grateful' to have a naked woman in front of them that they wouldn't care what she looked like!)
But the other side of it is that I don't feel I have the 'right' to act confidently or feel attractive anymore. I've 'learnt' that my body genuinely isn't acceptable and that trying to mask that with 'confidence' isn't the way to go. It feels like the physical equivalent of putting your fingers in your ears and shouting "la la la, I can't hear you!" It doesn’t change what you look like or what others see.
My partner has never criticised me. He is selective in his compliments though. That's fair enough, I focus on certain aspects of him more than others when I compliment him. But I do find it hard to feel confident. I don't feel I have the right to, I'm worried about attracting further criticism and it it feels, I don't know, disingenuous?
