well considering we're all consenting adults I think we can be as graphic as we like as long as everyone is ok with it. Personally I'd say keep sexual items to a minimum considering every character here IS below legal adult age. 

My guy's power is going to result in creating a lot of severely broken bones and injuries to some bad guys before he get's a little more of a handle on his abilities. So I'm all for some graphic violence and chaos. The book series I'm working on is YA so I'm limiting language and violence a bit in there but here we can be a little more lenient.
