So my friend is afraid to approach this guy because she's convinced she's a "slut", how can I tell her that it doesn't really matter?

I'd say this guy is high value by all means considered, he's tall, has a great career, looks wise maybe a 6 but could be better if he actually cared about his look. The only grey flag here is that he seems pretty conservative compared to most guys and doesn't really fuck around as much.

She's been beating herself over it for the past few weeks and it's getting on my nerves!!!

Are n-counts really that important for dating?
