Everybody here has forgotten the most important part of successful intercourse: proper choice of music. Don't put on your new One Direction or Linkin Park CD. Go out and buy something classy. RnB is a common choice. Do not, however, put on cheesy 1970s researcho music. That's just not cool.
Remember, the right music can transform a crazy, testosterone-fueled wrestling match into a sensual, romantically-lit night to remember.
Candlelight is optional.
