Pre fuck prep

I like watching guys fuck in videos but wish if they were going to use lube or condom i want to see it all.
My ex wife used to let me fuck her in the ass, sometimes on the spur of the moment but usually with some preplanning.
She would use an enemma by herself but when it was time for the fucking she would make a nice big deal of lubing up my cock, usually my balls too. She said it was because she was more thorough but I think she enjoyed doing it. I loved it myself as well as when she prepped her ass for my cock.
But I wish porn makers would include this in their fucking videos.
I am saving my butt cherry for some special experience and would want the prep for it to be part of the fun.
Anybody else?
Any links to videos where this is part of it?

As a total bottom, and frequent anal sex at least once a week my prep is always the same whether my buddy and I are planning a fuck night or not. I eat lots of veggies with high fiber and I enema daily with excellent results. I don't think he has ever had any scat on his cock after fucking me. As far a lube goes water based is best it doesn't take much, a little lubed finger fucking before plunging his 8 inches deep and hard. When he goes balls deep in hard and determined thrusts I cum with out touching myself.

yes a enema is a must. I do it 2 bags to make sure I am clean. U do need lube

I use the women's tube that's about 8" long with all the holes on the sides. I put it in when I'm on the toilet and swirl it around as I force the water and crap out. I do that a couple of times and there is less chance of some liquid getting caught up high and coming out and spoiling the mood.
