Membership plugin for semi-adult site?

Hello all,

I’m building a WordPress site for a friend who is a burlesque/fetish model. She wants to have a “members only” section on her site, which will have photos and other exclusive content in it. It won’t be pornographic, per se, but it will definitely be “adult”.

I’m trying to find a plugin (paid is fine) that will allow me to restrict access to the members only section of the site to paid members. I need the plugin to be able to interact with a shopping cart that a) allows for adult product sales and b) allows for repeated billing (i.e. subscriptions). So I guess what I need is twofold: a WordPress membership plugin and a shopping cart that I can work with.

Does anyone have any thoughts on how I can do this? I’ve been researching for WEEKS online, but I’m coming up cold.

Any thoughts or advice would be MUCH appreciated!
