Best I can do is a few moments of fleeting "fun" typically while in a 1-to-1 context. All other efforts feel clumsy and forced; I occasionaly enjoy things by proxy but in first person when "vibing" all I enjoy doing is abstracting over stuff (or joking powered by abstraction).
Since this is the case chronically, I have no frame of reference of what "play" even is, just an abstraction of it developed probably through osmosis. I'm on standard SNRI medication the past few months, which doesn't really make a difference when it comes to that.
