Flatline and Prolacin Relationship?

I'm trying to find out if what is happening to me is flatline or something else.

In the past when my PMO habits were "stable" for lack of a better word, what I means is short PMO sessions not everyday maybe every 2 days, I would say I had 8/10 erections.
However if from that point I started a new streak for about a week and then relapsed hard like, 2 hour PMO sessions multiple times a day for like 2 or 3 days, I would go straight into ED territory for a while (currently going through it) I thin it usually takes about 2 weeks of no PMO before I can say I'm back at 8/10 erections.

So what is happening here, I have read that this could due to a massive increase in prolactin that kills your sex drive, could this be the case, is prolactin elevated for as much as 2 weeks after ejaculation?
