I think if he's this diametrically opposed, your marriage won't last. Either, you'll resent him for blocking your kinkiness, or him not allowing you to be your true self, or you'll have zoo experiences and he'll catch you or deduce that it happens. If you really like this guy, you need to get him on board, or break up with him. If you get divorced years later over zoo experiences, he is going to feel like he wasted years of life. Not trying to be mean, I'm speaking from years of experience being married.
