In my years of sexual activity, I've done some pretty freaky stuff. I don't care where you put your fingers and have had some interesting experiences with rope. But, as Meatloaf said, I would do anything for love, but I won't do that. And my personal buck stops with taping my sexual rendezvous.
One guy I was with kept asking me to tape it when we fucked, and I just couldn't warm up to the idea. Sure, now that digital cameras are taking over the world, the odds of my sister innocently popping a cassette of me groaning into the VCR while visiting me are lower. But I'd only been seeing the guy for a couple of weeks. I wouldn't have trusted that guy to check his email on my computer--there's no way I'm letting his digital camera stay trained on me, even if I do see him delete the file.
