Is it true that people who haven't experienced a crash don't have fluctuations?

I took fin for 4 days 5 months ago and i got sexual side effects on the morning of the fifth day (libido, ED, pain at testicles, watery semen).

I still have ed and low libido.

I didn't experience the crashes that usually occur days/weeks after quitting, but rather the following day (I don't know if we can call that a "crash"?)

People say they experience fluctuations if they've had a crash. If that's not the case, and I haven't had a crash, what's the most likely scenario for recovery? (slow recovery? fluctuation?)

Thank you for your help!!
