A sexually awkward high school student begins giving out sex therapy at his school to help him get his dream girl

What sticks out for me is a credibility issue – why would anyone trust a ‘sexually awkward teenager’ to give them sex therapy?

In terms of it being a means to his goal, it’s also super creepy. Is that your intention? If it is, then you need to solve the first problem of credibility. We’ve seen movies where a psychologist takes advantage of their position to do something like this, but people trust a professional like that.
