If it is a painting, you can post it. As long as it isn't a real life photoWell, I'm not sure I can show it, because genitals, but someone once made a painting of me lifting up my dress and showing my penis. And also one of my pony plug tail draped over my penis (because then it's a cock-tail, get it? I'm hilarious).
Also, I used some chopsticks and rubber bands to make a tongue clamp... possibly suitable for nipples, just not mine.
