Sperm has a half life of 3 years, so most likely somewhere around six years.
A sperm can survive at a temperature of between 33 to 35 degrees Celsius.
Sperms survive 72 hours/ 3 days inside the woman's body.
The seminal fluid you call "pre sperm" has no living matter, sperm cells will survive for a short while on skin.

3-5 years
No it will not survive as SPERM only live for split of seconds.
Viable sperm cells have been reported harvested from cadaveric testes up to 48 hours post-mortem.
for about half a second.
It can't survive in a paper cup. To survive it must be kept at a very cold temperature and in a special container. At room temperature, after about an hour I think they start dying off at an exponential rate. They don't all die at once.
Y sperm can stay in womb for 36 hours after which it dies
3 years is an old fish.
