Amphetamine usage is a double edged sword. Sex when intoxicated is greatly enhanced by the limitless stamina and desire that speed produces. A man can virtually go all night before hitting the big 'O'. Unfortunately with heavy and prolonged use the exact opposite can transpire during chemical free sexual interactions - premature ejaculation. Just writing those two words makes me shudder.
Of course, this is not really a problem of great consequence for me in light of the fact that it's been nearly a year since the last time I was with a girl. But, a couple of my friends have freely admitted to snorting a pre-date, midweek line or two in order to provide insurance against sexual disaster, should they get lucky.
Now that is just fucked up.
