I swear they can sense when you’ve been getting laid a lot and it makes you more attractive to them on some subconscious level. There’s almost a feeling of momentum where it’s easier to get laid (with multiple women I mean) if you’ve gotten laid a lot recently. Whereas I know as a man, if I intuited or found out that a woman I was interested in had slept with four different men that week I’d be kinda disgusted. The key/lock dichotomy at play I suppose.
