As a woman, I don't understand this stereotype

"If you really made women orgasm, she wouldn't ghost you after sex" kind of things. But it isn't true in my opinion. Most women I know in my life who ghosted men after sex did because they were nothing more than ONS or pump or dump thing. It wasn't like he wasn't good at sex. Even though he have the ability to make a woman orgasm so hard to the point she faint, she was supposed to ghost him after sex

But what I cringe and irritated most whenever I reading some "dating" sub, most people immediately assume if men ghost women after sex it usually means that he got what he wanted so he bailed but when women ghosted men after sex it usually means she actually secretly wanted LTR but his dick was so tiny.

Why this logic?

Is it because men think their dick is so great to the point that any women who give his dick can't help but fall in love with him or he just can't fathom that women can separate sex from emotion?

Why women are not blamed for sexual deficiency if she is ghosted after sex? I mean...men also can ghost women after sex if she was bad at sex or her body was kinda ugly.

Why double standard?
