A few years ago, my wife gave me a vacuum cleaner for our anniversary. We have had more fun with that whole situation, but especially with the follow on where I was out of town (more than a year later) and she had to call her son to figure out how to turn it on.
Then, I saw the headline that men who vacuum have better sex lives. It is different than that: foreplay begins immediately AFTER the last time you had sex. If you make your partner feel appreciated, loved and sexy, it is certainly going to be better.
