As far as my understanding to the categories on E:<br/>Light = Nudity, light CONSENSUAL sexual content  (No forced or BDSM, etc)<br/>BDSM = Light + BDSM factors (Master/Slave, sexual torture but still consensual)<br/>Non-Consensual = BDSM + possible non-consensual situation (Rape, gangbang, etc) but nothing extreme like scat/vore/gore/Beastiality<br/>Extreme = Everything goes
