At what point does libido decrease

Hey all. I went 100 days without fapping. My libido seemed pretty up the first month peaking 3 week-mark maybe. Then kind of down after a month and back up a few weeks later.

Have you noticed that it declines after a certain point? Is this change consistent?

Just curious if I can expect my body to adapt to a new norm. I’d be curious what monks would have to say.
