Anything that makes you get turned off, is your bussiness. You should never stay in a relationship that doesn't work for you. Even if everybody in the world thought you were being nit picky, it's still within your right to terminate it because of it. But for your own sake. I'd comunicate this to them. I doubt they'll be offended.

Or you could just go for a Scandinavian Master. Showing off is quite a strong cultural taboo we have over here.
