The only way that would be possible is if the sperm entered into the vagina. If the underwear was moved away from the vagina at anytime that the boy ejaculated or after and the sperm entered, than yea, it is possible. If there is absolutely no way that the sperm entered the vagina, then the answer would be no. Your call, we were not there.
Semen is the clear while sperm is the white. The semen protects the sperm as it enters the vagina
To get pregnant, sperm need to be ejaculated near the opening of the vagina. From there, they can swim through the cervix and into the uterus, where fertilization may occur if an egg is present.
The urethra conducts sperm outside the male body. If pregnancy is desired, the vagina would be a useful place for the sperm to be conducted.
It is highly unlikely that would occur.
The sapling will undergo many changes before it becomes a mature tree.
It is not likely. The sperm would have needed to come in contact with her vagina. But by this point a lot of the sperm was probably already dead. I wouldn't be too worried but be on a lookout for any symptoms just in case by some chance it did come in contact with your vagina.
Semen is sperm, and all it needs to do to get a girl pregnant is be fresh and be introduced to the vagina. So yes. changes are just as much as if you would have ejaculated in the vagina. There are millions and millions of sperm a droplet of sperm and there only needs to be one to fertilize and egg and get a girl pregnant.
No. You can get pregnant when sperm is introduced into the vagina and although this is usually from penetration it can also occur in other ways. Sperm are motile (able to move) and sperm from someones hand or sperm that has been ejaculated close to the vagina could enter by itself
To kill the sperm, you would need to purchase spermicide and put it into the vagina before having intercourse. Drinking salt water will not have any effect whatsoever.
If there is semen on a surface and a woman applied her vagina directly to it, and the sperm hasn't been there very long (IE: Hasn't dried out and died), and the surface itself was not porous enough to absorb the semen, then there's a very, very slim chance some sperm would have made it into her vagina. However, it's not likely this resulted in pregnancy.
I don't know the expression, but from the words used, it would seem to mean male seminal fluid going into the vagina.
