Prostate massage instructional video?

I am trying to find a well done (read “accurate”) video to show a lady friend who has expressed a willingness to give me a prostate massage. She's a former nurses' assistant so no stranger to the male anatomy, but I would like to get her right on target (so to speak) without a lot of intervention from me (I'll be having “other things” to think about…lol). Anyone out there/here seen anything decent? (Just by way of information, many of the videos I've seen…admittedly from porn sites…show a gal with a finger up a guy's butt pointing towards his BACK!! Unless my anatomy is screwed up, the prostate is in the OPPOSITE direction (toward your navel/penis!!!) Any help (with the video, lol) will be greatly appreciated.

Good luck trying to find an “instructional” video of prostate massage. And a diagram or medical drawing of the anatomy is only so good. I have found just working with the lady in real time and describing how she can proceed step-by-step. Works every time and takes the pressure off the lady to be perfect…. and for you, a real entertainment.
