How do you shave your ass

Im not even gonna try to sugar coat this. have tried and tried to shave my butthole but every time I do I just slice myself. I tried a trimmer and the only thing left to do is wax. And yes, I have hair there and not only is it there it’s THICK black hair.

I dont wanna do that whole waxing thing, okay. The only way I’m okay with someone being down there is if it’s my doctor, or my partner. That’s it.

I know I’m not the only one out here with Ass hair and I know someone has figured out the art of self ass shaving and I need advice. Thank you.
