He might have left the club with a large group of women, but to assume he had sex with more than maybe 2-3 girls during that night is a stretch.
The typical refraction time for men in their 40's isn't that great. I can see him having sex with one woman, needing some time to recover before going at it with another, but then after that, I'd figure he was exhausted and probably fell asleep.
It was probably late at night. He most likely loaded up the booze and unless he popped in some Cialis or Viagra, he might have called it a night after 2-3 ladies.
