There are two possible reasons for this phenomenon, as far as I can surmise. One may result from the presence of dried body fluids in the end of the urethral orifice where it opens in the glans. This may stick the sides of the urethral orifice together so that when the force of urine hits it the stream initially opens two separate breaks in the sticky plug of body fluids. This has happened to me. Usually, by the time the bladder is empty, the two streams will have united to form one.
Two streams may also result from an unusual (but not unknown) anatomical anomaly in which there are actually two openings of the urethra in the glans. I have never seen this condition myself but one of my students (years ago) indicated that she had noticed the condition in her husband. If there is a name for this condition I am not aware of it.
