Olivia Attwood: Getting Filthy Rich - Series 3

Olivia meets the women who market themselves as MILFs and GILFs to help monetise their sexual services, including 71-year-old Caroline, who is hoping to pay off her mortgage thanks to a demand for sexually attractive grandmothers.

The adult industry has collided with the world of costume play. Olivia meets the content creators making a mint from dressing up and making sexual content while trying to find her own cosplay alter ego.

The classic porn star body is no longer needed to make big money in the sex industry. Olivia meets those who are monetising their unique body types in an industry that believes that bigger is better.

Findom, or financial domination, has a reputation for being the easiest way to make money in the sex industry, so Olivia delves into a world which promises the biggest cash returns for the least amount of effort.

Out of the three million plus content creators on the OnlyFans platform, only the top one percent are making the big bucks. Olivia travels to the US to find out how much the top earners are making.

From nights of passion to sending soiled underwear in the post, there's money to be made from the "boyfriend experience". Meet the guys coining it in and some of the women who are willing to pay for it.
