I don't like porn star porn, it's so fake.
My wife had the same thoughts about.
But once, she asked me to show her what I collected.
I couldn't hide my feelings about what turned me on. Like (some of) cuckolding.
Like your wife she loved homemade porno.
What I do look for is porn that fits a true event that, I, she or we have experienced that we have no pics of. These are not often easy to find.
We visited some different clubs. One became our favorite. I (we) wrote a (rather comprehensive) diary about our experiences.
Two lovers/bulls visited us at home so I could record her (or) experiences.
Because it was (of course) strictly forbidden to take pictures in these clubs I (we) didn't have visible "proofs" of what happened there.
I agree 100% with you that it is sometimes very difficult, in some cases even impossible, to find pictures that resemble our experiences.
