Sam, I have some additional tips that might just help 
First, maintaining perfect trim made it hard at first. I found that if I dropped my knees a bit, it would relax my bladder and made the stream come easier. Additionally, if your crotch strap is tight, it adds some pressure, which is hard to overcome. So, grab onto something, drop your knees a bit to relieve the pressure, close your eyes, and relax.
Another thing that helps me, and I really can't say why, is to check my SPG. It's somehow comforting to know that I have a ton of time to work through my peeing issues!
And as Lynne mentioned, it definitely gets easier with practice. After having not used it for a while, I'm a bit more apprehensive (subconsciously) and my body just won't let me do it....but after a few dives of using it, I find myself going multiple times in an hour long dive!
And one weird thing I've noticed is that when I have to go, but can't seem to get it going, I start to feel really "off"....like my diving is a lot more work and I feel like I'm not quite in control. When I'm able to relax enough and stop putting pressure on myself to go, I finally go....and then the dive turns around and is relaxing, simple, mellow, and way more fun!
Don't give up! It will come
