Hm...probably an easy one but:

What's a kink that, when you discovered it, gave you the most guilty pleasure? Not necessarily your favorite, or most arousing, but one that gave you conflicting feelings as you were aroused by it?

Uhm, it's hard for me to feel ashamed by a kink, but probably the one I find more difficult to accept is everything related to watersports (being forced to practice them, to be more specific). I'm not really sure when I discovered that "I liked it", it was simply used in many pictures that I found appealing, but more as the cherry on the cake, not as the protagonist itself.
It still gives me a sense of "taboo" and of "you shouldn't do that", but acceptation of the self comes into this shape, too. And let's be honest, it's funny to draw.

What's your favorite fetish? xD

Donuts.

Okay, all joking aside, my favorite is definitely petplay. It include a variety of kinks that I really appreciate.

That's a pretty good one! xD

Donuts are the best thing in the world, of course :P

Pastryphilia :P

How are you doing today? :P (yep, it counts)

Uhm, I was doing fine, then I got my hair cut and now I feel bad because now they're too short. Moreover I wanted them purple but they turned out some kind of Dr Pepper color :/ (#Firstworldproblems)

My grandpa always used to say that the only difference between a good haircut and a bad haircut was a couple weeks xD So it'll fix itself in a few days. No worries!
