Let's see.....
You can't be charged with Possession of sexually explicit materials as long as you do not possess any mechanically produced visual material. So, don't print out the pictures.
You can't be charged with Sexual exploitation of a minor because a minor typing on a computer is not sexually explicit conduct.
You can be charged with Dissemination of sexually explicit materials for possessing any mechanically, electronically or chemically reproduced visual image or material that depicts any minor, who the person knows or has reason to know is a minor, engaging in sexually explicit conduct. This includes pictures sent over the net whether you print them out or not.
Cybersex is most likely to result in the charge of disseminating obscene matter to a minor. This occurs when a person knowingly distributes, or exhibits or offers to distribute or exhibit to a minor, any obscene matter declared obscene, in an action to which he was a party, pursuant to subsection 3.
So, the two disseminating crimes are your biggest worry.
