Yes, pre-cum can contain sperm and you can get pregnant from that kind of sex play. Pre-cum is there when a man becomes aroused, long before ejaculation. Penetration is not necessary for you to get pregnant, all it takes is sperm to come in contact with your vaginal moisture and those little buggers have one thing in mind and that's to swim upstream to find the egg. It only takes ONE sperm to get you pregnant. If you're going to have this kind of sex play and pregnancy is not something you want, he should have a condom on as soon as he gets an erection or get yourself on birth control.
Here is a rundown of the life span of sperm.
1. Right inside the vagina or at the entrance to the vagina, sperm can live for a few hours.
2. Once it is in the female reproductive tract beyond the cervix sperm lives for 5 - 7 days (reason why you can get pregnant if you have unprotected sex at any time *including having your period* when you are not ovulating) You don't always conceive the day that you have sex, you can conceive up to 7 days after having sex.
3. Outside the body in air it has a very short life span because it needs moisture to survive. The general rule is, if there is wet semen the sperm in the semen can still be alive. Once the semen is dry, the sperm are dead.

It's been a long road getting from there to here. I know the wind’s so cold, I’ve seen the darkest days. But now the winds I feel, are only winds of change. I've been thru the fire and I've been thru the rain,
But I'll be fine. 'Cause I've got faith of the heart. ---Rod Stewart
Sometime in your life you will go on a journey,
It will be the longest journey you have ever taken,
It is the journey to find yourself!
