I feel really awful when my picture is taken, regardless of who keeps it, even with my own camera. Something something dysphoria. I do however love taking pictures, and slowly work myself up to taking them of people, who knows - maybe this journey leads me to taking pictures of myself. So far only individual body parts are okay.
Don't see much difference in naked or clothed, if something has to involve my body I don't care how much of it is visible, or what act I am being photographed in. It all feels equally wrong to me.
I did however take thermographs with a cheap thermal camera, these are so blurred I don't recognize myself that easily and the nerdy nature of it makes it interesting to me. So if I can find someone with a high-end thermal camera again, might give it a try.
