In feminist B--ch Magazine there is an article called Tree So Horny about a group called F--- For Forests, which explicitly uses pornography and sex to raise money to save forests.
I wonder why the same concept cannot be applied not to fighting against deforestation but to beat world hunger. I have already thought of a name for the group, Hedonism for Hunger where participants engage in hedonistic acts for the sake of raising money to fight world hunger. The money raised can go to the World Food Programme just the profits from Free Rice does.
Many people feel guilty engaging in acts of hedonism. However, if the hedonism is for hunger then that gives people a good excuse.
One of the main problems of the sex industry I believe is the fact that it doesn't cater to shy virgins. I suspect a large number of young virgin males and females would like to go to a brothel but are bothered by the high costs, the embarrassment, and the fear of being ridiculed for their inexperience.
High costs can be fixed through economies of scale. Thousands of clients can be lined up on a conveyor belt and a handful of sex providers can give the service to each quickly.
The problem of embarrassment can be fixed with guarantees of anonymity. A brothel may encourage all its customers to wear rabbit masks upon entry. In public someone wearing a rabbit mask will look like he is going to a fancy dress party, so the individual wearing the mask will not be too embarrassed.
