I guess, if your turn on requires "pretty people" and good camera work, then homemade stuff is going to be disappointing.
Lucky for me, the turn on is the people involved really enjoying their partner(s). I don't want to hear the predictable, "oh... oh... oh" of a porn start. I want to hear the muttered cussing of a real big orgasm taking over. If someone drops the camera in the heat of the moment, so be it.
Many of my own vids are poorly lit, only occasionally in focus, and I often put the camera down RIGHT when things get good... and they're still hot to rewatch, because I remember how much fun it was.
Even better though, on the rare occasion that I've shared a video of myself with someone else, it seems to have the effect of encouraging exhibitionism and lowering self consciousness. These are both wins in my book.
