Certain songs are written in a 'sexual' cadence...I don't mean obvious ones like those by Barry White or Marvin Gaye, but the rhythms are definitely timed to coincide with having sex. A couple are: 'Love, Rain on Me' by the Who, 'Feel Like Making Love' by Bad Company, 'Closer' (obviously) by NiN...
all start slow, build with driving beats, slow down again, then get to a crescendo and fade....
Only the first one was ever playing during sex, and it was coincidence...
did have sex during Monday Night Football once...scored about the same time Greenbay did
