If you go to a pharmacy you can purchase a plastic "pick" that tapers from a point, getting wider down it's 5" length. It's called a "MEATAL DIALATOR" and the purpose is to insert into your meatus (pee hole) to stretch out the urethra a bit... (aka 'sound'.) If you haven't done it before, there are LOTS of sensitive nerve endings INSIDE the penis and if you use lube and just go really easy with gravity, it feels quite amazing.
I had a slight procedure done which reqired me to abstain from all sex/jo for two weeks (I didn't make it) and to occasionally use the dialator to prevent scar tissue from building up while the healing was going on. The result was a very open tube, and when the prostate pump started firing the freeway was clear and I launched my wad much further than before. Perhaps the fact that there was some lube inside the pipeline also made the track a bit more slick.
You can see the dilator described and pictured
here. I'd say if you are going for a self facial and can't get yourself to that distance, give it a try...
