hey there
i like the site, kudos!!!!
in my opinion, you must continue to push hard with submitting galleries, posting to news groups (yahoo, etc) and other slow-growing vehicles until you are able to push-out and affiliate program.
you could try to create your linklists, free video websiites, etc.. all of the traditional things webmaster affiliates do. basically, create one feeder site and replicate the functionality to other feeder sites (all related to boobs).
i run a website,
www.ilikeboobvideos.com, which is a framework that would that would be great for you site.. driving traffic back to the paysite.
ideas are only limited to how hard you want to think on them ;)
peace
