Yeah before you work in the Indian sex industry you're going to need to start one up. I am sure there are people making money off sex and stuff in India, but at the moment making and sharing adult videos is illegal so you won't find too many jobs out there in the industry.
Instead, you're better off trying to film your own sex tapes and distributing them over the internet VERY SECRETLY. Just hope you don't get caught!!!
Owning and watching sex movies is legal in India, but distributing or selling them is illegal.
The alternative would be to fall into he "pseudo-sex industry" that is becoming popular in India.
Actors and actresses that may have acted in adult content abroad, but now are releasing to the Indian public "erotic thrillers" with no full nudity, but a lot of suggestions..
Movies such as Jism 2 are known for this.
