Even without bitcoin, porn sites are already present even in an ordinary payments. Aside from using other forms of paying. I think people were more focus on their investments rather than wasting their money with porn sites.

Although the porn industry is the biggest and probably one of the most influential in the online world, they still have to look forward and seek for new features. Same goes for gambling and other traditional industries.
I believe it is a matter of time until BTC or any other altcoin would become a standard method of payment at least as CC / PayPal
