Very bizarre but low stakes situation led to almost complete fluency?

Very bizarre but low stakes situation led to almost complete fluency? So, I'm a 23 year old bisexual man, and met a girl on Hinge. She pitched me the idea of doing a "bisexual bachelor" date; going on a date with both her and her gay friend simultaneously, seeing which I liked more, then choosing one at the end. I agreed to it because it seemed fun and would at least be a good story. Yesterday, the day came for it to happen, and we all met up and did the date. Details aren't too important for this sub, but the aura wasn't that's awkward over all, and everyone though the situation was funny (this was the first time they did it too). The part that shocked me more than the date, though, was that I was basically fluent the whole time. I have a mild-moderate stutter, and I'll usually have some sort of stutter or block every two or three sentences at least. I think I stuttered one time in the entire hour and a half date, and I was talking nonstop. Even words that I basically can never say without stuttering (like my job as a biomedical engineer) I got through with no issue. For possibly the first time in my life, I felt like I was the most socially capable person in the conversation, and it's not like the other people were particularly awkward. I can't believe that this is how it's like for fluent people. The only other time I've been able to be almost fluent is if I'm very drunk and I was stone cold sober. It also wasn't a particularly good fluency day, I was stuttering through the rest of the day. The whole situation was bewildering; has anyone else experienced anything like this, where your stutter almost didn't exist but only for one particular event?
