There are actually four different fluids emitted when a man ejaculates. The first fluid is completely clear and that is a slippery fluid generated from the cowpers gland which is located at the base of the urethra. This is usually secreted when a man is aroused before ejaculation but not always.
The second fluid which is involved is a white-clear fluid from the prostate. This can sometimes be slightly yellow as well. The third fluid is the sperm which comes from the vas deferens after it has left the testicles. The sperm is usually white in colour depending on the health of the sperm. There are actually several different types of sperm.
The fourth and last fluid emitted would be spinal fluid which is mixed with the prostate fluid and can be yellow or clear but when mixed with the prostate fluid and sperm is usually more white than yellow. The texture of this cerebral-spinal fluid is almost identical to that of cooked salmon.
