He actually complained about the way your hair grows back? Yikes. I'd be telling him he's a little too picky and nature happens! WTF does he expect you to do shave twice a day? Sure stubble can be scratchy, but we all deal with it. It's not that much of a problem surely. And you shouldn't have
to shave the second day. It IS irritating to your skin, so tell him to maybe remember that you are a person too. Anyways, I hope you do what feels best to you.
No, my partner has never complained about something so petty. The only thing to this nature he has said was that when I epilate and he goes down on me the same day, my skin is slippery and tougher to hold onto.
