The ejaculate is very much like prostrate fluid. It is usually clear, or milky and as thin as water. It does not have the look, smell or taste of urine. It is almost odorless. The taste varies, depending on the time of the month and diet, and possibly other factors, such as amount of stimulation received prior to ejaculating or time since the last ejaculation. It can vary from an almost honey sweet, sour, bitter, or a combination of these tastes.
Even though it is ejaculated from the urethra, it is most definitely not urine. It is absolutely impossible to pee during a orgasm unless there is a weak pubococcygeus muscle. This is very important, and it is important for the female and her partner to both understand this. The pubococcygeus muscle contracts when terminating a stream of urine, and is the muscle which contracts during orgasm. This contraction helps prevent retrograde ejaculation (ejaculation back into the bladder), and of course prevents the bladder from draining during orgasm.
