Do you mean rough as in sandpaper or do you mean the appearance is rough looking? I agree that circumcision should be left to the adult. It shouldn’t be something done at birth.
Wash your penis with water only, at the end of a shower rinse your entire genital region with running water only, the other essential is making sure your entire groin region, and in particular the tip region of your penis is completely dry using a clean dry towel that only you use.
Get yourself some quality liquid Coconut Oil or SHEA butter and apply a light coat, I would suggest around 3 times a week, apply after you have completely dried yourself from taking a shower.
