Welcome BlueBuddha!
Regarding affiliate programs.... I've heard several differing opinions about the best time to approach this end of your website... I will say that the one piece of advice that I have always been given is to make sure that you can offer webmasters something unique, something that will make you stand out from another site... whether that be payouts, content, etc.
With so much out there in adult online, it's definitely tough to make sure your product stays top of mind with webmasters... but it's not impossible! You can learn a lot here on the boards, and don't be afraid to ask questions!
Best of luck to you!
