I thank my parents for leaving my foreskin alone, I am grateful for what I still have. My male partner, on the other hand, is circumcised and I think his cock is very sexy all the same. He seems a bit intimidated by my foreskin sometimes I think, lol
My female partner has made some mention of his technique being hampered by a lack of foreskin (he has much less freedom of movement in his balls and shaft, and the angles that work best for him don't work so well for her), but we both find him very hot all the same, he has quite a different, more frotty and sensitive approach.
I'm involved in raising a child, and I've noticed that kids in the bath like to manipulate themselves. This seems like a perfectly normal developmental stage. I imagine that parents who get uptight about masturbation would discourage this kind of infantile developmental activity, which is where I speculate that foreskin problems begin to emerge (lack of cleaning leads to filth and infections, lack of the stretching activities causes a non-retractive foreskin). I don't know if any genuine study has been done in this area though.
I was raised, I like to think, with a healthy attitude towards sexuality, never discouraged from play activities as a child, never abused, no religious guilt etc., and my foreskin has never been a problem for me (other than a zipper once or twice). On the other hand, I know a guy who had a strict religious upbringing (a particular culture notorious for reinforcing unhealthy sexual attitudes) and his foreskin is seriously dysfunctional - non-retractive and alienating to women. I doubt he is alone. Hence another fear about leaving the foreskin on.
Worse case scenario involving drastic liberties taken with an infant that I know of: google Dr. Money - a tale of circumcision gone wrong and subsequent medical experimentations of dubious merit.
I agree with the idea of consent, any non-essential surgery performed on an infant's body, boy girl or intersex, is a cruel violation of their rights.
Some people have no concern for the rights of others and they reveal themselves with their attempts at definitive and authoritarian-seeming discourse-ending opinions, as if they have shares in a patriarchy that lets us all down, or something.
I know plenty of young men who have had an adult circumcision and they are happy with the results they sought. But I also know of guys trying to grow their foreskin back through painful methods. I have a suspicion that male circumcision at infancy leaves a faint but lasting scar not just on the shaft but also the sexual psyche.
