Yes I've done that a coupla times on my scrotum-wattle - it clots pretty quickly, once was the day before but it never happened, other was the same morning but Busty Anita didn't mind when I told her. I realised I was holding the shaver at an angle, I use a No 1 on pubes and balls.
But on balance I'd say the healing time is probably longer than any WG who sees it will be prepared to risk going anywhere near it, works both ways don't forget!
