I'm not PC. She sounds like a tease. They do exist. I suspect that if you wouldn't have been afraid, if you wouldn't have reacted in horror when she pushed you away, she may have gone through with it.
This is like that anecdote a ways down the threat. The guy goes out with a girl, treats her great, they make out. Later on she ghosts him basically, acts like he sucks and then loses her virginity shortly to someone else.
What's going on here? I think the GenY men have become horribly confused about aggression. They think that they can get sex without going through the different stages of calculated aggression - libido and sexual aggression. The truth is that all sex requires an element of actual, but very low level, fear. I know, crazy, but it's true.
Sex requires a situation where someone is literally allowing you to enter their body. From experience, this is an aggressive actions. Your cock just doesn't slip in and then softly exit afterwards. It's very aggressive. The problem is that with sex you have to go to the line - that line between aggression and actual violence. There's a line and that line is the turn on. Every person has their line and they want desperately to balance on that tightrope.
GenY men, a lot of them, seem to go at this from a female perspective. Become friends and then when that is safe make your move. That doesn't work. Here's why. When a woman becomes your platonic friend they are purposely turning off their sexuality so that you can be friends at all. They are suppressing it or don't feel it at all. Men keep their attraction going. They don't suppress it and frankly these types of "male friends" are basically friendzoned whether they know it or not. The women get freaked out when you hit on them.
Here's the hard truth. You can be the best friend of a woman that you fuck. It's possible BUT, and here's the crux for most people, that friendship occurs only AFTER you are not really friends but only potential lovers. It's a different dynamic. Yes, there are contrary cases where you are friends a long time and eventually somehow fall in love. Not typical though.
You have to get through that period of lust, where you aren't really friends, you are lovers only. You get through all of that and you are left with lasting love and a good friend. A friend that is really deeper than any other friend or relative you could have. This is b/c you have gone through the part where you weren't friends but only lustful lovers. GenY seems to want to skip that part and get to the long last relationship part. They seem afraid and I understand that - that period is very exciting, scary and frequently very disturbing. You can't control yourself, you are addicted to someone literally (chemically). It's a catastrophe. GenY doesn't want to lose control but that is required.
