Girls - count how many sexual (full sex, not playing around) partners you have had?
Ask your partner how many they have had (same criteria). (he will try to brag and lie - remember past convos!!!)
Most of us women will have had more sexual partners than our partners, though there will be 'bucks' to the trend.
Disclaimer - Do not tell your partner you have had more sexual partners than him if he didn't already know it.
