If you are infected by Covid and produce natural antibodies, will occasional exposure to Covid ensure regular production of antibodies?

Not sure if I worded the title correctly, but I was wondering how antibodies and resistance to Covid works. Take, for instance, my experience with the virus…

* I was vaccinated in August 2021.
* I was infected by Covid-19 in October 2021. No hospital visit or monoclonal treatment required.
* Antibodies are said to be good for 90 days. 
* I chose not to get any boosters. 
* I have not been as “safe” as one could be, and have been in largely unmasked crowds on occasion. I have been to stores, out with friends, on vacation, etc. — always following Covid guidelines, but when given the option not to mask up, I have chosen not to. 
* Luckily, to my knowledge, I have not been infected by Covid-19 a second time. 

If your body produces antibodies after infection, is it possible that continued exposure to Covid would ensure your body continues to produce antibodies?

Why would continual exposure to Covid *not* act similarly to a booster?

The biggest difference is a booster doesn’t actually infect you, it only instructs your immune system. Continual exposure risks both a dangerous illness and continuous virus mutation that increases the probability of more dangerous variants. 
For example BA.5 is more transmissible than the original variant you were vaccinated for and there is no guarantee that vaccination protects you from it. Hospitalizations have skewed from 90% unvaccinated last year to 60% unvaccinated now. We want to avoid continuous exposure and subsequently continuous mutation if possible.
