Am I the only one for whom POIS is alternated by a period when orgasm doesn't give any pleasure at all? It's called ahedonic orgasming. I do ejaculate but it gives no feeling at all. Purely mechanical business.
I know this can take a couple of weeks / months.
The funny thing is that in these periods, my POIS is gone: no pleasure, no pois.
This seems to have interesting impact on the understanding of POIS.
