Why is semen cold?
if it is too warm then the sperm inside will die
A ordinary cold makes you contagious for the first 3-.4 days and if you have sex with someone and being that close then you can give it to them too. Just like you can by sneezing on them while passing in the hallway. The semen or vaginal lubrication do however not transfer a cold through the genitals.
If there is a small amount of semen on the fingers and he fingers and it was really cold outside and the semen hit the air could she still get pregnant?
Semen has to come out one way or another, so it may come out in he is in his most relaxed stage, when he is asleep. from there, he has a wet dream. a wet dream is when a man (or teenager) gets a fantasy in his dream and he nuts on himself, leaving his boxers cold and sticky in the morning. it stays inside the body and doesn't do anything
