What sorta subjects are you uncomfortable drawing but do because there is great interest in them?

If I was uncomfortable drawing it, I'd ultimately say no. There's actually a few things that I personally don't have any real care about whether I draw them or not, but I worry that if I begin to draw them, I'll attract a certain crowd who will commission me for nothing but. I like to draw a range of things and I don't want to get stuck into drawing one particular fetish. GIVE ME ALL THE THINGS!
