I've had MDMA like this. No regrets.
Years later I found better - a 1 hr long full body orgasms - thank god it was alone in kutis seperated by forest - i sounded like meg ryan in "Sleepless in Seattle" for about an hr or two each day - but where did I find this? In myself doing nothing other than scanning my body in meditation and letting the breath calm me.
Externally: it was in a monastery meditating with a group of celibate monks in the middle of the forest - and that is the foot hills - not yet "jhana".
This is properly why people are celibate - they are not idiots. I found the cause for that. It wasn't in self denial or asceticism but actually - to reach something deeper.
There are of course people celibate for the wrong reasons. BUt I got an idea of why. Also in finding this pleasure its based directly on the lack of interest one finds in sensory pleasure which ironically frees energy that produces pleasure in ones senses and body - I see also how the ability to sort of "feel out" or feel oneself into this is a great service to society as the act of practicing this is finding the internal harmony in oneself and that manifests as external harmony.
This is why people were properly monks and nuns - but also the source of the institutions wisdom and power and later domination by the types that just want power and so on.
