So here's my opinion, and just like assholes, everyone's got one (not as nice as mine however)!
While I too, shave my sack, taint and asshole, I keep the rest "high and tight" but nicely trimmed in. So what I'm saying is that my wife doesn't really give a shit what my asshole or taint looks like because unfortunately she won't do any butt stuff with me. I keep it looking nice hoping that it gets appreciated for you!! I'm picky about what I want to play with, suck and ultimately fuck!!
So basically DO YOU BROTHER!!!
