This applies to guys and girls. Say you're dating an 8. He/she's hot Say you find out about their past partners. Would you rather: If you're a guy: - Find out they're all douchebags - Find out they're all pretty cool, good-looking, successful guys If you're a chick: - Find out that they're all ugly chicks, like 4s - Find out that they're all gorgeous I figure it could go either way. On the one hand, it would be cool to think you're the hottest person your SO has ever fucked. It increases your value in their eyes. On the other hand, it shows lower value in your SO if you find out they only fucked losers before you.
