as some people said here that it is pornography which is real that it is not worth betting on because it violates immoral norms or even has a huge negative impact out there.
sometimes a gambling addict who has been in gambling for a long time feels bored with the types of bets he plays every day and wants to find new sensations as mentioned in the OP article. from this experience gambling addicts also sometimes have a high interest in trying new types of bets maybe until sex wants to be at betting. whereas on the other hand there are still many types of games that are really worth betting on.
Well, maybe they want to find a new sensation in playing gambling but should choose another gambling game instead of having to bet on sex games that might be banned or not added to casinos. And if none of the casinos want to add it to their roster, maybe gamblers can find a local casino to add to their playlist.
for offline casinos it might be possible to add this type of bet but for online casinos it is definitely not possible to add this type of sex bet because it has violated immoral rules for me.
so there's no need to be curious about this type of bet because this is just a rumour.
