You should've stayed in control, man. When you lost control, she lost attraction for you (if she even had any, to less info to tell).
You were not respectful to the fact that she wants to be fuucked, she just does not wants to be seen as a sllut.
She probably said that because she didn't want to come across as a sllut or whatever. But the interaction was INDEED headed towards sex and you can bet your ass off that she wanted it. She wanted you to lead her trough the experience, but you became immobilised by her statement and lost control. Thereby she probably lost all respect for you. This is why she won't text you anymore and found a guy who was more dominant, leading and sexual.
I would've responded with something like: Why are you talking about sex so soon? I'm not finished kissing you.
Then pull waaaay back, create a vacuum, so she'll start leaning in again, and then move things forward once more.
Then get her so turned on that she can't help but to enjoy herself with me
Move on and learn from this.
