By smut, do you mean fictional erotica? I used to, a long time ago. Yes, I'd read your stories. I find it fascinating how people have such different experiences.
It depends on what's considered 'perfect' by the people evaluating said encounter. If most or all of their criteria are met, then I presume their answer would be yes. Despite saying that, I believe there is not.
Do you have a fantasy that would be your ideal / perfect scenario?
