It took some clever positioning (laying on the bathroom floor, feet up against the base of the sink) and a lot of patience as you are slowly able to reach your lips to your penis. I was only ever able to get the head into my mouth, as the discomfort of being in that position for any extended time was outweighed the novelty... but I can tell you, there was nothing like the first time I was able to suck my own dick until I came.
... kinda wish I could do it again, but I have a feeling it would require me getting some ribs removed before I'd be able to reach again.
