I prefer myself to be completely bare. However, I think I would freak someone out if they visit the area for the first time and not find any hair. So I transition my trimming, so that it gets shorter and shorter every time.
I prefer hair to shaved, but I think it should be groomed. Body hair is natural, but that doesn't mean it shouldn't be trimmed, just like the hair on your head.
I like to be shaved when engaging in anything sexual, but I don't like how I feel the day after I shave, it hurts... lazer hair removal would be a blessing lol.
I prefer my boyfriend Trimmed... as far as the balls, I haven't noticed much hair on them and for that, I am happy.
It really depends, honestly. On women, I sometimes will occasionally like the aesthetics of it being shaved, but I have no preference either way. I think that trimming is good for hygiene, but other than that, no preference really. I personally trim.
