I don't know about the lap dance thing. You would look beautiful which is a natural but perhaps POV would be the most ideal scenario. Plus Mr. Anonymous would be best suited to be silent during the shoot if such a thing is possible, no easy task I am sure
As for the peeing. Like others, it is not something I necessarily gravitate towards but for those who do enjoy it or have a fetish for it then doing a video could bring in a new stream of members which of course would be awesome.
If you feel comfortable enough, give it a try and see how you feel afterwards. It shouldn't turn away your already established members because they'd support you regardless. It shouldn't be all about the content, but the lovely lady involved in said content.
