Not porn, sorry, but one of the rare all male characters in my stable regardless: this is Dogstar, my "furry answer to Superman" that refuses to remain in the back of my mind. Originally a German Shepard, I decided to make him a Doberman partially because it's a breed I don't usually see done in a heroic light very often and partially because I (mistakenly) thought they were naturally stubby-tailed, which would work wonderfully for a canid in a cape.
I don't have any plans to do Dogstar porn, but if somebody saw fit to try and persuade me, I might be able to talk him into posing...LMAO
