OP, you get a lot of shit here, which is really unfair.
I now how it is when someone goes against your set boundaries, chipping them away piece by piece, until you don't quite remember you set them in the first place.
I don't get those people on here acting like you had initiated the sex, then there's no hint to that at all. 
Meet the next guy in public, and do not go anywhere private with him.
It is not safe.
Granted, being alone with a man is never safe, but this specific kind of asshole might lose interest after three dates with no opportunity to get you into bed.
If you want a quick shag that's perfectly fine and dandy, I'm not judging you, but if you put out on the first meeting no bloke is going to think you're girlfriend potential.
Utter bullshit. He never wanted a relationship, simple as that.
He "put out on the first meeting", too. Or, more precisely, he pushed her into it.
Men that are worth having aren't damn shitty sexist assholes who would judge a woman for the very same thing they do themselves. Easy as that.
