I'm not rly into exhib, the themes of exposure or the risk of getting caught etc don't appeal to me, I'm more into the adventurous places angle. But many of the pics of that couple are undeniably exhib themed, which is a funny outcome.. Art is a strange process? I think when I'm drawing them fucking on a beach, I'm not thinking "...and someone could walk around the corner at any point!" I'm thinking "wouldn't it be nice to fuck on a beach". Subtle maybe. At least my understanding of exhibitionism is that being seen or potentially being seen by others is a part of the kink.
I'm into lots of other stuff, some of it I draw, some of it I don't. Lately I've been thinking about matched sets; twins, uniforms, etc. It's sorta objectifying in a way that's compelling. I want to draw more stuff with power exchange, but I think that sorta thing is more suited to comics where you can establish a context.
