Cuckold Husband Rule 6: Always always keep your cock and balls shaved clean.
My girlfriends like to see a bald cock. Maybe it reminds them of the ones they sucked when they were young. But, a woman loves to suck on smooth balls.
It is also a lot easier to put a cock ring on and to tie your balls up. That way, you won't have your pubic hair jerked out.
Also, dear husband, your itty bitty cock will look a lot bigger and women like bigger cocks.
So, hop to it and shave your cock and balls!
