The penis -- in its unaltered state with an intact foreskin -- is pretty clearly designed for sexual activity where it is inserted, and where it can move around during sexual activities without a need for any special assistance. Not only do you not have to do anything at all to your foreskin at all during any kind of intercourse , it's designed in such a way to work optimally with that activity. While we need to be careful how we talk about genitals , sex and design, since we can't consult with the designer and so can only theorize, we can safely say that even if someone chooses not to reproduce, the penis clearly has a lot to do with reproduction, and the way it is, foreskin and all, is conducive to that purpose through vaginal intercourse without aid. Given the massive population of the planet, and knowing the majority of people with penises worldwide are not circumcised, you can rest assured the uncircumcised penis works just fine in that regard. While the practice of circumcision dates back further than recorded history, in most of the world at any period in history it has not been the norm: save for those of us of Jewish or some African heritage, many of our oldest ancestors were not circumcised and their penises did the job just fine, hands-free.
