It's a mix between the dynamics of a turbulent flow, and surface tension. Also, I notice the urethra is more of a slit than it is a hole, so the stream exits the tip with kind of a vertical cross-section that collapses on itself, if that makes sense. Uncut guys can control the shape and angle of …

The Short Answer

It's a mix between the dynamics of a turbulent flow, and surface tension. Also, I notice the urethra is more of a slit than it is a hole, so the stream exits the tip with kind of a vertical cross-section that collapses on itself, if that makes sense. Uncut guys can control the shape and angle of their stream with a lot of precision , though.
