I doubt there is even one tiny morsel, but have left room for possibility in my wording.
Once, over a decade ago, I caught Heather Hunter twisting her head to push the head of a penis into her throat. It was the one thing I was missing information wise. It was incomplete information though.
I have found I often need lube, and that my throat is drier than it feels to me. Porn never showed me that. I'm still learning. For a few years, my wisdom teeth were in the way. I learned that after they were removed. I had no idea they were still growing and had gotten much larger than when I first learned to deep throat. Porn didn't help me with that. I have learned that my esophageal opening must not be symmetrical. If the corona is, I have to have his help pushing down on my head as I try to angle it to my right side and give that little head twist or it won't go in.
All I learned from Ms. Hunter was to twist my head, which really, from her example, just looks like enough. I had to learn from experience it is not. Experience would have led me to that conclusion eventually anyway. My mouth is a fucking rock star.
Where did you get the idea of deep throat from the start?!!! from school or parents?? I doubt!!
and here, you are talking that porn didn't help explain exactly how to perform a certain act, but didn't porn ever give you a thought/an idea that you tried to include in your real sex life? NEVER?
