Is it normal ocd with gently knocking on my head/wood

I dont even beleive in that shit about jinxing and stuff.

lets say we are going to the beach for example.
"it says its supposed to be nice and shady out today"
*knocks*
"now you dont have to lather me in a cm thick layer of sunscreen."
*knocks*
"well, im pale enough and i dont burn easily anyways"
*knocks*

i know, wtf???
