Exactly, there should be no shame to having done nude photos. You should revel in them. They are your glorious past, your story, and who you are.
I have an ex that did nudes in the past (back in the 35mm film days) and it didn't phase me one bit, in fact I thought it made things hotter. After a while a friend found out about that and was like "dude, are you ok with this? Like it's your woman!"
At the time I laughed it off and didn't care but evaluating it under a more informed lens today I realize today that it was the patriarchy tell me that this was "my woman and I had to keep her body under wraps."
