First off, I'm kinda annoyed with a lot of videos because they are so unrealistic. That said, I favor large enemas, bag enemas, and administered enemas.
Not really a fan of the Japanese stuff either. I like the medical and bdsm scenarios best (Stonefox was one of my faves). As I said elsewhere, I particularly enjoy some sadism when I watch, but I don't like fakery. I used to watch the Collector's stuff quite a bit, but solo doesn't turn me on nearly as much as a forceful male giving to a female, IF it's realistic. I think I've watched nearly every enema video made, and it's now pretty hard for me to find anything new that makes sense. In person, I am quite kind. In my fantasies, many of my scenarios tend to be fairly bdsm. I've never figured out why that is, because I respect others, especially women, and try to be kind to them.. A twisted spot in my brain, eh?
I sometimes watch while receiving, if I am solo, but now my wife gives to me when I ask, so I'm absorbed in the experience.
When I give to her, it's prep for later play a lot, other times when she needs a good enema.
It is obviously a major fetish of mine, but so are many other things. Watching is good. Receiving is better. GIVING is the pinnacle...
