It does cause chafing if you do a lot of walking around within the first few days, although for me all the chafing only ever happens in my crotch under my balls (I might as well shave everything since shaving the asshole is 99% of the work). Powder solves it but also if your job doesn't require you to do miles and miles of waking a day, it's a non issue.

Imho, the advantages of shaving my ass outweigh the negatives. Wasting toilet paper is bad. Streaks smell. The problem with bidets is you'll only ever get to use one if you install one in your home. People always tend to refute every claim that it's more hygienic, and while I'm not here to argue that, there are situations where not having all that crotch hair results in less body stench since it can be wiped easily. For further b/o control you can apply deodorant to your balls and that patch of skin above your dick and it's really effective as long as you aren't planning on getting your dick sucked.

Everyone is free to do whatever they want with their ass hair but every comment section about ass shaving is full of people that think it's bad. It's important people are aware of both sides of the story.
