your urethral sphincter contracts so semen doesn't enter the bladder and vice versa
apart from it spraying everywhere the flow itself is much more slower than normal even if i just have morning wood, but if i were to actually get rock hard by masturbating and then tried to pee i literally wouldn't be able to pee even a little bit, i actually tried, so it stands to reason you wouldn't be able too pee at all during sex either
