Hello :)
So bascially I'm a 23 year old male and throughout my entire when I get exicted I have the urge to clinch my body, shake, squeeze my hands and make random noises.The best way to describe it is this trapped energy/pressure inside of me that I have to release and it just feels good. No one has ever said anything to me because I come across like a normal run of the mill person, and when I get excited around people I can suppress my actions. When i'm on my own I will move my hands and make weird noises, bascically see the full extent of it.
Another thing that I do which may be related is I tend to say things out loud to myself and repeat them like 3 or 4 times, kind of like a reassurance thing. Not sure if that would be related low?
