THis is totally unrelated to the whole shaving issue, but I had a boyfriend who was the same way. In fact, I had the threat that I’d be DUMPED if I didnt’ shave that “area.” Back then, it never was a concern for me but since he was my first serious boyfriend, I guess I had to do what I can to keep him.
Like you I agonized over that area. And my skin is ultrasensitive! I mean I tried everything - shaving, waxing, rotary epilators - anything that would keep my hair away. And I often told my ex boyfriend back then that I had trouble with shaving and such because of my very sensitive skin. Of course he wasn’t so compromising about it and he went ahead telling me how I should do it.
To make a long story short, I eventually dumped the sucker. I’ve been relationship free for more than a year now, but at least I don’t have to put up with picky, shallow men who tell a girl what to do in order to please them.
Hair is there for a reason, and if he can’t accept that, then how else can he accept you? 
Just a thought…
Another thing… If he is SO anal about how you should do your hair? Make him a compromise… If you have to be all clean shaven down there, MAKE HIM trim, shave, wax, etc… On his own. Double standards are just a pain and it’s not fair if it’s ONLY THE WOMAN who does the hair removal!
