Taste is a null argument, imo, because after a shower, it tastes like literally nothing for a few hours. 

Feeling is also a null argument, imo, because all he has to do is lick something.

I’m guessing he doesn’t eat ass either. Your bf sounds lazy. Personally, if it’s physically not hurting me nor putting me in a position of danger, I’d do just about anything to make my gf happy.
