Is it normal that i draw ecchi foxgirls pretty much anywhere?

When I say foxgirls, I mean girls but with fox ears and tails. I don't venture into furry territory with snouts, paws, and other shit. I really like drawing them in suggestive poses, although I'll still draw them sfw, or draw plain human characters. Only rarely do I draw H though. It's not as if I get especially aroused, I just find them pleasing to look at I guess.
I also draw wherever I feel like, such as in class or in cafes.
Sometimes I'll lightly draw pictures over my friends' notes (like a watermark) or draw in pen on their notebook back covers. Some people say it's the fact that I draw them well that's weird. My Japanese friend's mom commented that she always knew I was a closet pervert.
