When a man comes, his heartbeat is jacked up to an average of 180 beats per minute, his breath rate increases to 40 per minute and his systolic blood pressure leaps to 100,
The muscles at the base of his penis contract rhythmically (some say to the beat of James Brown’s “Sex Machine”) at .8 second intervals, usually three to seven times. The average male orgasm lasts for fewer than 10 seconds.
