Calling it a jinx just wasnt technically correct. A jinx means causation between A to B but it also implies that there's no clear explanation why. Just something almost supernatural or pure luck between A and B. For example, some performers wear certain color underwear for their performances. No rationale reason, but they see a pattern between A and B.
Here, there's a clear reason why between A to B. Jaekyung wins his matches after sex because a person often performs better when they're less stressed. It's like doing better on an exam after a good night's rest. I'd be hard pressed to call sleeping well a jinx to success.
I had guessed this in a previous post and some ppl were disappointed by the idea. I think it's because we expected more from this 'jinx' since it started everything. But I can see why JJK calls it a jinx also. Performers and competitors can be superstitious when it comes to their pre-show/match rituals to boost success and they find comfort in routines. To someone as hellbent on being successful as JJK, I can see why he's come to call sex a jinx. His character seems to find comfort in a strict, repetitive routine, i.e. working out, drinking milk, sobriety, wearing cologne, etc.
