Success being measured by number of partners is odd, imo.  I've known plenty of guys that would have plenty of casual sex with anything that moved (bombshell to gutter trash) that were just out for the numbers game.  I've mostly had long term relationships (meaning >1 year) with few relative partners in comparison. I'm certainly bias, but I would rate a long term, stable relationships as a better success than raw number of partners.  Either way, hammies are going to lie.  Unfortunately, some of the guys I knew would likely be adding points to the female hammie's "score" table.
