Not being able to bend your arms round the wrong way, none of that bullshit. I mean the kind of stuff that happens without your consent, anomalies caused by your neural network being up the swanny etc.
This hasn't happened for a while now but I just remembered it.
I would frequently get a kind of tremor in my right ear at exactly the same time as my right nut tight started itching. I used to quite like it, the tremor would start fractionally earlier than the itching. Good times.
And just to keep it erotic I'll share the fact that, these days, I can get a dead cock if I sit funny. Like when your foot goes dead if you sit on it. That's much less enjoyable.
Anyway, enjoy your lunch.
