Being shaved, or at least really trimmed is good for us married straight guys too. I started well before getting married though mainly because I stay physically active. I like to run and bike a lot, so I've got solid, muscular legs, and I sweat a lot during these activities and even in my occupation. I cannot stand the hair down there trapping sweat and growing all sorts of bacteria and other grime. Yea, I shower frequently, but when I'm on the job, I cannot just tell everyone "hey, gotta stop for a moment and go shower, my balls are getting sweaty again" Trimming things up down there makes it much more comfortable and less smelly...same thing goes for the armpits as well!
