Scat play is considered taboo. What else?

I love BDSM & the endless possibilities.

and anything involving animals.

 
Then there is the whole cut and bleed scene, but blood makes me queasy.

 
Some people do like scat play (not me) but hepatitis is no fun.

 
Shoving no end of implements up the rectum can also get dangerous.    Just ask any proctologist.

 
I'm sure in time someone could fill a book with no-nos.    

 
In fact, someone did, a Herr Kraft-Ebbing, some many years ago, in fact.

Anything can be considered "taboo," but in my book that word has in its orbit mostly incest-related stuff...however, I'm of the mind that what *others* might consider taboo could very well be - and more than likely are - normal and fun for someone like me. For instance I love GS (giving/receiving) but some think that's the absolute limit, they'll never do it. Scat isn't for me lol but I can appreciate how some might like it. To each their own right?
