Boyfriend armpit fetish

My BF has armpit fetish.

He isn't so forcefully addicted , still he had clearly described his preferences and he wishes me to keep my armpit hair.

As it was winter , even I didnt mind, and had grown pit hair considerably. I rarely wore sleeveless also . Now it has started becoming warmer , and I tend to sweat in my warm wear, I doubt whether I create a body odour issue at my work place, although I use perfume .

I know these are my choices , still I don't want to be rude with him. I don't feel to seek his permission and all for this , but he shouldn't feel like I just dont care for his fetishm.
