Here are my current partners and the best websites to advertise on your adult website(s). From my experience, these are the most trustworthy and offer the highest and most consistent payouts.
Chaturbate - Hands down the best cam site out there. All amateur, truly live, and completely free. The hottest cams go to the top of the page with thousands of users chatting and watching for free. But they can't resist to contribute to the live action. These ads will effectively complement any adult website. More Here.
iStripper (formerly VirtuaGirl/TotemCash) - The time tested home of iStripper (previously VirtuaGirl/Deskbabes) Allows your users to have naked and stripping women as well as lesbian duos appear on their desktops at regular intervals. Consistent revenue and fits in anywhere. More Here.
