Childhood suppository memory turned sexual fetish. But why?

I vaguely remember getting suppositories as a child. I didn't like them! I remember crying whenever I got one because I'd imagine that they hurt me back then, although I do remember getting aroused and getting an erection. Why do these thoughts turn me on so much now? When I see an attractive lady, I think about her taking suppositories or getting suppositories or her giving me a suppositories. Can anyone explain why this is so? I'd love to hear some possible explanations.

I'm not well-versed in psychotherapy, but maybe that's how the body responded to stress or trauma — replacing a traumatic or unpleasant experience with something that excites.

I just remember my dads large fingers making sure they were all the way in..

Same here. my earliest childhood memory is having a white pill painfully inserted.

Back then I had psychotherapy with a guy whom I told him most of my traumatic experiences with enemas and suppositories, and the pleasure I feel now from them.

He said that maybe I had an involuntary orgasm, who knows. Anus and rectum are very sensitive places.
