TIFU by conditioning myself to get a boner whenever I fix the printer

When I was a teenager I got super bored and decided I wanted to see if I could get a fetish on purpose. I set up an experiment to see if I could get a fetish for something extremely non-sexual if I tried hard enough. So every time I wanted to whack it, I ignored looking up porn and instead looked up computer insides and maintenance imagery on google and tried to jack off to it. I did this for like a month or two and then forgot about it because it wasn't working, and now like five years later I realise I accidentally pavlov'd myself into associating sex with machine maintenance. The real kicker is that I'm the family's computer guy so I had to go to my grandma's house to fix the printer there, and I had to pull out the toner drum and I legitimately felt like I was doing something perverse. I could not stop getting nervous the entire time I was there because I was anxious about my poor unsuspecting family somehow finding out that opening up the printer gets my dick hard :/ TL;DR Jacked off to computer parts when I was like 15 cause I was bored and now I'm scared shitless of fixing my grandma's printer in case I get a boner 

EDIT: Sorry if any of my friends who know this about me saw that i put this on reddit for clout. Thought id at least get something out of the debacle
