If you make a post asking anyone here for advice about "this one girl" then you have failed to understand what TRP is about.
There is no girl who is The One. There is no single magical female whose transformative vagina is going to bring the light of True Love into your life.
TRP is not a tool for convincing your one magical princess to love you. Even if that is your goal, TRP requires that you lay down the groundwork for doing otherwise. That means building a lifestyle that leaves your one magical princess acutely aware that she can be replaced in a heartbeat.
The easiest way to sell that idea to a woman is to just up and do it. "Next her" is pretty much always the right answer to every version of the "I'm new to TRP and I need to use TRP methods to nail down this one girl who I fucking worship and whose asshole I would totally lick clean if she asked me to" question.
It is painful to see these posts. If you feel the need to make these posts, then frankly you need to keep reading rather than start writing.
