Swinger community website (Not a dating site)

I am looking to create a functional similar website like couplestouch.com. Another functional website would be [login to view URL] or even: lifestylelounge.com. All are different looking websites, but ones that cater to adult swingers in a community. Can not be anything like a dating website. There must be an option not only for Male, and Female, but also (most imporatantly) couple. Should be easy to navigate around. If possible would also perfer a site with two languages: Spanish (mx) and english (us) As this will be based in Central america. Should have ability to create each type of account upon initial joining. I do not (initially) need all the bells and whistles nothing "fancy" yet, but should have some sort of membership maintenance as well as payment system. See searching capabilities on LL for example and also picture posting and display is important. I want something simple. Please do not just use an existing "dating" template you've used with other customers. Has to have specific COUPLE functionality in mind. Again this is going to be a "base", and will add upon as time goes forward. Not looking for maintanece just starting up. Thank You very much.
