Do you have the doubts?
It’s not that hard. I fold some toilet paper, press it against the area that needs to be cleaned with the balls of my fingertips (the part where my fingerprints are,) and press while wiping.
Men and women still need to get their nails clipped/removed as much as they can. Why is that? Because our anal spots need to be cleaned thoroughly from the inside and then outside (Having long nails can damage vaginal or anal organs internally). Here is my method of doing that and I hope you will not be disgusted. Think, apply and then decide if it is one of the most efficient and secretive methods in hygiene world.
