If you want more than what the free version of Red Light Center offers then you'll
need to come up with the VIP. VIP membership lets you get naked and get down.
You can't do that with the free version. You'll also have access to the VIP only clubs found around Red Light Center.Unlike Second Life, Red Light Center is a completely adult only community.
