What about the well known honeymoon period when people first get together? Can't get enough of each other for 6-24 months, then it tends to fade.
Our bodies could just adapt to the new hormone levels. Some guys who let their E2 run up as high as it can go say at first there are symptoms, then they go away. That seems like adaption or receptor desensitization.
If you don't eat for 24 hours, the first meal tastes better than average.
I get the feeling you will be chasing a ghost, if there was a magic level then some men would be at it already.
