Wow! I thought you were gone forever! I even forgot I wrote this message!
Okay, so the erect penis thing is with a dA site admin? You know, I do agree with you. Sexuality is part of adult human life, and an erect phallus is a definite representation of this. Problem is, our society is set up, due to the enforced guilt of taboo and sin brought on by a strict history of right wing religion and politics, to perceive sexuality as something negative and 'immoral'. Time for a change. I think that your art portrays sex in a way that the viewer can relate, but it's not 'in your face'. It's subtle and abstract... I can't understand why anyone would have a problem with your art, no matter what it portrayed.
There are galleries full of real photos of real aborted faetuses here on devART, but they don't want to see a part of the body that half the population posesses, and the other half can appreciate? Fight, man! I got your back!
