There is an additional variable here that can result in an unintended phenomenon I call “sprinkler dick”. Occasionally (often after sex but not exclusively), I will be standing to pee and - all other things being equal - my initial stream will surprisingly come out at an almost 45 degree angle (always to the left for me). At other times, this phenomenon will manifest as the initial stream coming out bifurcated, forming a V (and not as a result of any stuck pubes).
I have no solid explanation for why this occurs, but it is very repeatable, to the point where I now automatically sit down to pee after sex, because I can’t be arsed mopping up the bathroom floor.
I have no idea if this phenomenon is unique to my physiology or is something that other men experience.
When not actively passing fluids, the male urethra is almost always collapsed. In that state, it is easy for "precious bodily fluids" - or just the normal moisture of its inner lining - to dry out at the external opening, sticking the urethra's walls together and producing such effects.
