nice introduction Sam, but may i add that scat play is more safe than CIM or sperm swallowing, unless there is blood in the scat.
I provide scat play many years and when i started i asked doctor in Austria about risks and he explained me everything.
My female scat slave Isabelle-extreme offers 2 scat sessions/day in Austria and does this obligatory weekly tests and she is very fit. She swallows piss & scat from her clients, but she never allow sperm near her mouth or pussy and ass.
