How long does it take semen to harden?
So I'm writing a story. The character is a man, and he ejaculates onto a wet shower door. (The translucent glass kind.) How long will it take the semen to turn cold and harden?
Here are the Google terms I used.
"how long does it take semen to dry" (This turned up results for how long it would take sperm cells to die.)
"how long does it take semen to dry stain" (This turned up results for how to get semen stains out of various substances.)
"when will sperm leave a stain" (Same as above.)
Here are the Web documents I used.
Yahoo! Answers: How long does it take for semen and sperm to dry outside the body? This asked whether or not a woman could get pregnant from sitting on a semen-covered toilet seat.
MedHelp: How long can semen survive outside the body?
Yahoo! Answers: How to get semen stains out of the carpet?
Slate magazine: Why does semen glow in the dark? Interesting, but not very helpful.
I am not a man; neither do I have access to a man whom I could ask. Any help, especially first-hand knowledge, is greatly appreciated.
