(Im talking for my own experience in the business) Majority of men who are not circumcised dont clean under the foreskin. And Im talking about grown men. Approximately 40-% of my clients are circumsied. On that 60% left ; approximately 10% clean under their foreskin. Also, it was said before but a lot, A LOT of them dont wash in between their butt cheeks. Im not doing anything in this area but we can SMELL it. They think they gonna turn gay if they put soap and spread their butt to clean themself in the shower. Im not kidding. Its mind-blowing.
