OMG, yes. Always be careful of accidents when you have an erection. When erect it's like a bone and can break like one. It can't exactly go in a cast so it just heals in whatever shape.....often right angle. Every time I see a porn scene where a guy with an erection jumps on top of someone I think of it. Peroynie's can often be "rubbed out" eventually, but broken dick is harder to recover from.
