Sounds like this is one thing that's pretty much universal across the board.
We were fortunate to have a little break in the middle of our first play session to take a shower. It was a good chance to talk privately and make sure neither of us secretly just wanted to go home, and to check that we didn't need to discuss any of our rules. After round 2, we just slept. The next morning? We fucked, worked out, talked about all the fucking over breakfast, went back to bed and fucked, talking about it over dinner, met our friends for drinks, ended up playing with them again, then fucking each other, then falling asleep and fucking again in the middle of the night... I haven't gotten to the "the spirit is willing but the flesh is weak" stage for a long time.
To your question, a lot of our conversation was about things we'd seen but weren't completely sure what had happened. How did she feel about a woman going down on her (good, it wasn't as uncomfortable as it seemed in her imagination, but she prefers cock), did I really like watching her swallow someone else's cum as much as I told her I would (almost to a fetish level), was getting spitroasted the way she thought it would be (great, she wasn't ready for it to end), did I feel as intense about looking her in the eye while I fucked her friend from behind and her friend's husband fucking her from behind as she did (yes), did it turn her on to see her friend get off with me (embarrassed yes). It's always been the technical details about sex that get us to have better conversations about what we're actually doing and why. I thought it was going to be a much more delicate conversation than it actually was, and I was surprised by that.
