OK so when you said "If it has not reached sexual maturity do not have sex with it, or fantasize about sex with it," you were wrong? Could you be more accurate about what types of "its" that have not reached sexual maturity is OK to depict in sexually explicit drawings, and what type isn't? Why are slugs OK, but non-human aliens are not OK? Say, if there was a story about humans that were genetically engineered for deep space exploration and reached full brain development by the age of 5 along with an accelerated education regime, but otherwise physically developed like normal humans, would it be OK to depict sexual acts between those people? Or how about if someone was having sex with a sexually immature slug, but then it turned out to be a human child disguised with a cloak that made them look like a slug later on? Or what if it was actually a sexually immature slug, but was disguised with a cloak that made it look like a child?
It's real simple. The kind of it I was talking about was kids. Human kids. Don't fuck 'em, don't think about fucking 'em, don't fantasize about fucking 'em because if you do that you're a pedo plain and simple. You can blur the lines all you want with drawings, similes that look like kids but aren't, slugs in disguise or whatever but if you are attracted to the idea of sex with children then you are a pedo and you need help. If you want to pretend you're not because they're drawings and no real kids are getting hurt then you're a pedo in denial.
