I doubt it was just that.

Your friend probably upped the ante by adding mouth and anus. To keep a fella, you have to go "all-in" these days, so to speak.

She probably checked his oil for him.

I doubt that was the reason

So, I’m not crazy proud of it but I slept with my now boyfriend on the third date two years ago and we are going strong. He’s three years older than me and has had like 7 partners before me, but I stayed a virgin until 26 when I met him. Yes it was early on in hindsight but it just felt right. All this is to say that sometimes when people find a partner they’re compatible with in all ways, not just sexually, it works out for them. It doesn’t have anything to do with you or your body per se, and people’s lowers aren’t the sole key to “making someone stay,” per se. It’s usually about a meaningful connection
