To be fair I still do these things but only when I’m alone.
Personally I love finding big puddles and then dig drains with a stick or my heel and watch the water flow.
Also love to throw a piece of wood into water and then toss stones high up in the air and try hit it imagining it’s a warship I’m trying to bomb.
Then also without going into details there are some pieces of clothing I would like to wear but don’t because they’re considered femine or gay.
As a pretty much nobody streamer man on twitch, not even affiliate yet (I’m so close yet so far), I also struggle with social anxiety but find that streaming has been pretty easy for me. It’s different than actually having to interact with people face to face, so it feels more like talking on a thread than irl interaction.
Of course that’s just my experience and my anxieties may be on a much lower level than yours, but I recommend giving it a go if you think you’d have fun with it!
