6 or 7 paragraphs and that's what you managed to take away from my reply?
"Tutorial" might sound a little clinical but have you seen the video(very NSFW) I'm referring to? It's not exactly step by step instructions on how to assemble an Ikea dresser.
Now I don't know about you but I wasn't born knowing everything about vaginas, or how to go down on a girl. Hell, there are plenty of people out there who don't fully know how their own bodies work. So some friendly advice from a woman, porn star, and sex educator was very helpful back during my awkward teenage years. Obviously it's not a step-by-step, one size fits all "recipe", but it did help me become a better partner and I introduced my partners to things even they didn't know they liked.
As far as listening to my partner, exploring, discovering, asking her what she likes, that's what the entire first half of my comment was about.
But you kinda skipped over that and focused right in what I was super insecure about.
