What I'm advising isn't aggressive at all. Your actions should be effortless, or at least appear to be. That's what she wants, a man to conquer her in his sleep. It only sounds aggressive to you because it's so against your passive nature.
And your mindset about this is super warped. You've put too much work in not to fuuck her? So what, she owes you? Do you act nice to women so that they pay you out with sex? Ever heard of cutting your losses? Your time would be better spent with a hooker.
You've dug a hole and made a particular impression on her, 'passive cuck'. You're not going to be able to flip that instantly and do everything in a boss manner to diick her down properly, especially with her doubting you every step of the way(because of the first impression). You're asking how to salvage this because you have no clue how to be a boss, forget faking it. That stuff should come to you naturally, it shouldn't be this big deal where you're sinking a ton of time planning things out, especially if you see nothing long term.
The effortless boss pipe laying mentality doesn't come overnight, it's a lifestyle. Forget the outcome of this one girl and focus on the process. You say you want to be a mack, good, now trust in the process of becoming one and execute. And again to be clear that does not mean desperately try to fuuck this girl. It means challenge yourself in all aspects of life. Work on your body, your mind, your clothes, your career, your social circles, until women are child's play by comparison.
Find dragons to conquer and let women be your joy when you take a break. Don't make women out to be the dragons, that's thinking like a cuck.
