Advance orgasm help!!

So, I have tried and tried and tried to achieve orgasm through gspot stimulation but nothing has worked. I need help.

First of all, I feel like I can do it. I get that intense urge to pee, but nothing happens after that and it's frustrating. How do I push past that into orgasm?? It doesn't feel like it's building an orgasm either...but idk I could be wrong. Maybe it feels different from a clit orgasm, IDK! Halp.
