Woman do not produce semen.
You mean, "Semen". Semen is the whitish, thickish fluid that carries the sperm cells (short for spermatazoa) out of a man's body. I have heard it said that semen is somewhat nutritional, but there can't be much taste to it, or the sperm could not live in it. Semen is completely harmless when swallowed.
No. As long as there is semen ejaculated into the vagina, there are a possibility of pregancy.
Not with his own semen. Though if he came into contact with another man's semen (having sex with another man or even a woman who recently had sex), then the "foreign" semen could impregnate the woman.
Well If youre a woman you should not have any semen. so if you have semen you are a man.
Yes. A tired man can still produce semen. It might take more effort but as long as he can put semen into a woman's vagina, she can become pregnant.
it lives out of the semen tank up to 15 minutes because of the dramatic temperature drop. so be quick with your transfers!!!
Your question is not entirely coherent. Although, I think you're asking how long semen can be detected in the vagina for an analysis. Semen can live up to 5 days in the vagina and still be analyzed.
no
It depends on how spread out it is if it is spreadout it wil be dead within seconds.
The only way semen can be found in saliva is if the woman swallowed a mans ejaculatory fluids.
As long as the man is STD free swallowing semen will not hurt you. A 51 year old man is not different than a 21 year old. The woman's health is not compromised by the age of the man.
