Hello, I would be happy to assist you.
The urethra, the tube the urine comes from is inside both labia. The position you are in, whether or not you are leaning forward, the position of your urethra, and the presence and length of your pubic hair can re-direct your urine stream. If you have had a normal pelvic exam recently, generally, there is nothing abnormal affecting your stream. If you have not had a pelvic exam in the past year, I would recommend you obtain one to make sure there isn't anything like an abnormal growth near your urethra that is affecting the direction of your urine stream.
