When I was in high school we were playing with microscopes and supposedly some bitch swapped the inside of mouth and put in on a slide and everyone seen live sperm cells kicking around under the microscope.
Sperm are alive and active as long as they are wet - some say about five days. They live only a few hours and even less than that outside the human body, exposed to the open air.
Our biology teacher told us the same thing. Supposedly it happened when he was in college. The professor asked for a volunteer, she volunteered and right there on the projection screen the whole class could see sperm swimming around in her saliva.

when i was in uni we were learning about tastebuds and where they are situated on your tongue. anyway, there are many that detect salt on the tip of your tongue, and a girl in another lecture (same lecture many times to different groups) apparently asked, absentmindedly "well then why doesnt semen taste salty?"
as if that wasnt horrific enough, the lecturer said "well, usually, the semen is deposited in the back of your throat..."
