I'm making my first story on Chyoa, and on the side it says that underage sex, bestiality, and extreme violence aren't allowed. I like getting really specific with the rules as it helps me understand them as well, and I just like nit picking things in general, so I have 2 questions about the rules when making a story. Does the underage sex part still apply when in terms of transformation? Like an 18 year old transformed into someone younger than 18 years old, but his mentality and state of mind continues to stay at the level of an 18 year old? Does no bestiality mean that humanoid animals having sex with humanoid animals or with humans aren't allowed?
Speaking as someone with around a years experience on the site: In the first case: NO. That is not allowed. Characters must LOOK, THINK, ACT, and BE minimum 18 years old WHEN engaging in any sexuality. In the second case, Yes: it is allowed. Anthropomorphic animals feature in sex scenes with humans all the time here. The judge of if it is acceptable is the "Harkness Test", illustrated bellow: So, if the creature's an adult of its species, capable of giving informed consent and has communicated that consent to the other partner: it's all good.
