Regardless you have to. There is a thing called smegma. And basically it's like all the diaper hairs/ dead skin and anything go into the pores around the circumcision area. And looks like zits if you don't basically wipe it everytime.
Ipull it back gently everyday , the skin will heal in the position u leave it Use a&d or Vaseline to keep it moisturized Or else you’d have to get him cut all over again 🙁
So the foreskin on an uncircumcised penis is like a hood covering the whole head so it pulls back pretty far. I don't know if they left a little skin there or if it's like a crease between the head and the shaft. Either way, it's important to clean every crease and crevice. So yes, I'd be sure to clean it. Just be gentle because some parts may be sensitive if it hasn't been cleaned or exposed much.
