Not what I hoped for

So I took my first self administered injection last night, bumped it up to 100 from 50 initial units like the urologist said, results were just OK. Injecting that much made my dick feel odd. Everything began with a blowjob, which is one of my favorite things, and she is very good at it, but it was very uncomfortable, like my dick was too full even though i wasn't fully hard. Mix is 15/1/0.01 definitely going to have to get that adjusted. I do feel like injecting 100 units is too much, not of the medication, but too much liquid to inject in your dick, especially when different mixes have people injecting as little as 10 units. Gonna have to call my urologist.
