Doesn't anyone think it's silly to expect to find a person that rates a 10 on all facets you require in a partner? 10 in looks, sense of humor, intelligence, personality, style, tennis playing skill, horror-movie-watching-desire, etc.? As such, don't most people seek out others to fill the gaps in these habits or traits that they want to rate a 10 on?

You play tennis with someone else, you watch the horror flicks with other friends, you seek out intellectual stimulation of a certain sort from those who can provide it.

Why should we expect our partner to be our only resource for sex?
