you have artistic freedom to do whatever you want, so, if you want to do it then do it but pre-warning, you might get some backlash from people who get butthurt when an artist tries to do something out of the norm
Well it's not up to us if you make porn of your characters or not. What you do with them is what you do with them, no one should stop you from doing what you want. Unless you've brought a character from someone and they don't want porn made of the character then yes, you shouldn't do it. But if you made the character then you have all rights to do whatever you want.
Oh, I misunderstood. If you want to do it then go for it. I just found it weird that it looked like you wanted us to make porn of our characters instead of you asking something like," Should I make porn of my characters?"
