Sexual market value, sexual marketplace value (abbr. SMV) or mate value is a single number representing someone's desirability or value in the sexual market. SMV is somtimes expressed through the decile scale, (i.e. that person is a 9, he's a 3 out of 10 etc.). Though while the decile rating often is only used regarding looks, SMV always includes all things that make someone attractive (so also income, status etc.).
