You produce semen all of your life.
No, the color or composition of semen does not vary based on a person's race. Semen is made up of sperm and other fluids produced by the reproductive system, and its characteristics can vary slightly from person to person but are not determined by race.
Some seem to have a bit of a hang up about it. other are not all that worried. It is good from the mans point of view if the woman is not worried about getting semen in her mouth though. The same as it is good for the woman to feel that the man has no negative feelings about her juices so to speak.
Not immediately, but sperm dies when it dries up.
60-70 of semen made up of = -10
The production of semen is an ongoing process.
During a woman's most fertile periods (most likely to become pregnant) a white substance is released from her uterus which may end up in her panties if she is not wearing a panty liner. However if you two had unprotected sex and you came inside her, Once she stands up gravity happens and your semen slides out of her vagina although it may have already done its work. (hope this isnt the case). If neither of these scenarios are your situation and you think shes hiding something normally a womans "secretions" as you say ..dry up and look like yellowish/white clusters of goo. A mans semen is likely to look wet and or dry unto the fabric of the girls panties. Hope this helps :)
yes semen will show up in your drug test because of your vanginal jucies.
Break up with him.
I really really hope this was a typo and you meant "semen in the egg". If not, read up on your anatomy:]
The answer depends on a number of factors. On a dry surface sperm are dead by the time the semen has dried. In water sperm will live longer. Inside a woman's body, sperm can live for up to five days. If you have unprotected sex even a few days before your partner ovulates, there is a chance of a pregnancy.
It mans shut up
Yes it can. Semen appears a pale greenish yellow under a blacklight, just like most white things glow bright purple. Clean it up before you invite your buddies over to show them your new black light. No. I own a blacklight and something that produces semen; I can attest that my semen does not glow any color before or after it has dried.
