I don’t know. I find it to be a helpful tool. There’s definitely times it’s wrong (very very wrong sometimes) and there’s sometimes it’s right. It’s up to the user to figure that out.
Maybe I’m old and cynical, but I don’t take anything I read on the Internet, especially something automatically generated, at face value. It’s just another tool I could use to help get to the answer I’m looking for.
Worth mentioning most partners I had preferred either completely shaven (like smooth to the touch) in the area above the shaft or a bit longer but trimmed and neat. The problem with no guard buzz in that area is it creates stubble that can be grating on the clit during women on top sex.
