I know the 70s are remote in time to men 30 or 40 years younger than I. Back then, everybody pnp'd. Not so much on meth, but MDA, a forerunner to ecstasy. I've done my share of MDA. I tried meth-not my cup of tea.
IN THEORY, I would still pnp. But even back then, it took me a couple days to recover from a party. Now, I imagine the recovery time would be more like a week. I would think twice about throwing away a week of my life for a night of substance-enhanced sex. The cost/benefit analysis doesn't make sense.
