I've noticed some members asking about positions/activities. I hope this helps.
Not only will it help it might give us some new ones to try out. I hope the ladies don't mind. Heck maybe there are some in there they might want to request from us.
Oh, and click on any one of them and you'll get a nice little animated how-to on the position and a narrative. Some interesting posts from people to on their own personal (maybe not so personal) experience(s).
