Sex games used as bets are like humiliating humans indirectly because people will see performances where it is a private thing between men and women. And let's hope it's fake news that just wants to sensationalize or maybe the one who created the idea wants to know how far the response is from readers or even gamblers.
There could have been more stakes than that if sex games were in casinos because people wanted to try something different that had never existed before. This can make their imagination will expand to create new forms of betting.
It seems that this is just nonsense or a rumor that is spread, but there is no strong evidence that sex will indeed be made into a sport.
I don't believe what the OP said.
Maybe this news is made by irresponsible people with the aim of causing debate.
Anyone would never want to take risks by betting on sex tournaments.
