WTF
I can understand strangulation/breathplay being on the banned list as people have died from that stuff. But since when has fisting been life threatening? How many people (male or female) have been rushed to hospital (or even died) after being fisted during sex?
And why ban female ejaculation but not male? Is female ejaculation not considered normal or natural?!?
As to the rest of the list: WTF?!? If the participants are all consenting adults, what's the problem? Just because it's not your cup of tea doesn't mean no-one else will like it.
