If your lover took you out to the city's finest restaurant night after night, wouldn't you soon be craving burritos and beans at your local Mexican place? Sure you would, and this ennui with routine is true for sex as well. Romantic, meaningful sex is wonderful--but sometimes it just seems like a lot of work. Consider this probably not unfamiliar situation: You are horny, but you don't have the time (or desire) for a prolonged love-making session. You just have an itch you'd like your lover to scratch, then you'd like to get back to your spreadsheet...This is the moment for a quickie.
