I mean, you have to be pretty comfortable and somewhat casual in an orgy - it isn't like someone is going to tip their top hat and say "Perchance, madame, may I gaze upon you from below whilst delivering my tongue?"

I mean, maybe someone would, but it would be with someone they know and kind of jokey about it.

But this:

obviously I would never touch or invade someones personal space without verbal consent.

You might not, but some do behave that way. Its gross when it happens, and generally speaking, that person wouldn't be invited back (as long as the person running the event is made aware).

So really, yeah, you'll need to be comfortably casual. You're going to have sex with them, not ask them to take you to prom first.

Oh thank God someone recognized ancient arcade etiquette in my joke. I thought for sure someone was going to like roast me in my comments saying "This would never work What are you talking about that's not funny".

It takes quite a bit of experience to accurately read a situation, especially if things are getting kinky

I've hosted things, where I basically wasn't playing because I was making sure that everyone else was safe (first and foremost) and enjoying themselves

I've seen inexperienced DMs either freak out, power trip or miss things

One of the easy ways to dip your toe into things is to attend a few munches and non-play events. You can get a feel for what it's like to start or join conversations with people in a sex-positive environment

@Neu I'm now thinking about you going as someone's pet. They can take care of all that for you, in line with your wishes and desires, and they can also guide and help your preferred partners in how they ought to handle you once you have agreed with them who it is you'd love to play with?
