Well, I usually steer people away from the less pleasent issues, while going over the standard rules, like safe words, telling someone where you're going to be, when, and set up a safety call so you can reassure her that nothing went horribly wrong. I've also supervised scenes between couples who wanted to explore "extreme" kinks preferrably this side of dangerous, or abusive, and all that other safe sane consentual stuff the'd put in the pamphlets if they'd print them for me. {I've kinkoed a lot of them for Parties of various types.}
IME, people don't ask me about stuff likeat unless they're curious, so it's like expasnding someone's knowledge of the kind of musik you like, start with the more acessible bands/songs/aspects and so forth. Having tried most of the kinks I've heard, and thought of, at least in roleplay, I can usually encourage this in my little introductory lectures.
This works for bisexuality, swinning, cross dressing, other material fetishes, furry, age play, fluid worship/humiliation, Dominance/submission, asphyx (Don't be a
Dead Goon) spanking through suspension, and caning.
