Sperm Lifespan

[lostangel2130]

Hi.. This was my first time but I touched my boyfriend's penis and I felt something wet. He said it was precum. I freaked it and wiped it off right away. It's been two days and this came up in my head. How long can a sperm live on someone's skin?!? I know there's a chance that there could be a sperm in the precum. I'm worried that there's a chance that it could have been alive when I went to take a shower. I'm quite worried that the sperm was still alive when I took a shower and it somehow got inside of me. I really don't want to get pregnant or anything. I've been stressing so much about it. So here are my questions:
1. What is precum?
2. How long can a sperm live on someone's hand?
(I have gotten many different answers with this question and I want to know the truth.)
3. Is there any chance I could have gotten pregnant because of the situation I am in?

All I did was poke his penis.

I didn't have sex.

Before you have sex you should get more sex education.

Precum is pre semen. Just like when a woman gets sexually aroused so does a man. This happens so there will be lubrication so a couple can have intercourse.
I can't give you an exact answer as to how long sperm lives outside of the body. I've read that it can be 5 minutes to an hour. I question the hour because sperm needs a moist environment to survive. At an hour it would be dry and dead.
No, you could not have gotten pregnant by what happened.
