Well, in chemistry, viscous means the thickness of a liquid etc. here is an example
Syrup is more viscous than water.
Hydration. More water in your system, more fluid will emit during ejaculation. Not necessarily semen count, but capacity of fluids total. The reverse is appropriate too... And no liquor doesn't count.
It could mean that there is a low quantity of sperm cells in the semen. Or it could mean that the semen was exposed to air, as semen gets thinner within a few minutes.
It means you wank way too much and theres no seed left in you.. give it a couple of days and your body will recoup
Thick semen has high viscosity, whereas thin semen has low viscosity (more watery). If the viscosity is too high, spermatazoa in semen are less able to move (toward the target ovum).
The saline water is more viscous.
By viscous, I think you mean viscosity. Viscous is a adjective referring to the thickness of a substance; therefore, yes, ketchup is somewhat viscous.

it mean that it can not be compressed
You are either not fully matured, or you are ejaculating too often.

Have a look here http:/dictionary.reference.com/browse/viscousViscosity it how thick or thin a fluid is.The thicker a fluid is the more viscous. If the fluid is less viscous it is thinner. A fluid is liquid AND gas. If a fluid is hotter is gets less viscous but if it is cooler it will be more viscous.
Fascinating question, friend: My first question to you would be: "Safe for what?"Semen varies considerably in color, consistency, amount, smell, etc., I would assume by your use of the word "rubbery" that you semen is thick and viscous (that mean's sort of like oil- in that it sticks together rather than being watery or runny). As long as you don't have a sexually transmitted disease, your semen should be safe for sex and whatever else you might be considering. Again, the only real criteria for safety of semen with regard to sexual activity is the presence of disease causing agents, including sexually transmitted diseases and other illnesses. Also, viscous semen may indicate that you tend to be somewhat dehydrated, that is to say, you may not be drinking enough water. You can't change most of the aspects of your body associated with sexuality. However, you can influence the consistency of your semen. If you drink a healthy amount of water, then you can produce somewhat more semen and it may be somewhat viscous. Also, the viscosity of your semen can be influenced by your diet and the frequency with which you ejaculate; i.e. the more frequently you ejaculate, the less viscous your semen tends to be.Lastly, in a very real sense, and this is important, semen is never "safe." It can cause pregnancy and a lifetime of heartache and regret, as well as being the source of life for children. So, in that sense, semen is like anything else that carries with awesome power, it can be used for life-giving good or profound evil. So I guess the best answer is that while rubbery semen may be normal, semen is never really "safe."As with all things health related, if the consistency of your semen remains an area of concern for you, talk to your health care provider. And remember, semen is never really "safe" no matter what its consistency, so be careful out there.
That doesn't sound important to me.
It may mean that you need to ejaculate more.
Visious
This fluid is called semen.
You Don't Do Anything That's How Semen Smells :)
