Precum, by itself, does not contain sperm. However, precum might CARRY sperm.

You know how rivers carry stuffs from upstream to downstream, right? This is similar to that. Precum is released near the top of a man's urethra (the tube that semen travel through), at the Cowper's glands. Usually after a man released his semen (or cum), he urinates, which supposed to clear the urethra of leftover sperms.

Well, this isn't perfect and sometimes we still have sperms leftover even after urinating; sometimes we don't urinate after ejaculating at all. So if your boyfriend has ejaculated before he had sex with you (for example, masturbated or had some sex earlier), then his precum might pickup some leftover sperms from his previous ejaculation.

=================================

You've got about 4% to 27% per year, depending on perfect use vs. typical use (Source: PlannedParenthood, a well-known non-profit reproductive health provider), of getting pregnant with precum.

If you want to be safe and even safer, then BEFORE you two have sex, have your boyfriend take a trip to the restroom and urinate to wash out the leftover sperms.

More information on the withdrawal (pull-out) method here: Planned Parenthood

And here's a chart (click on the pictures to read more about each birth-control method).

University of California, Davis also has a simple chart for birth control effectiveness if you want a quick look.

Note: Keep in mind that both the pills and the withdrawal methods don't prevent STD/STI. (I know that other methods exist, but these are the most common, right?) So if you want to be safer and extra-safer, then combine a male condom into whatever birth-control method you're using or planning to use (e.g. condom + pills, or condom + withdrawal; maybe even condom + pill + withdrawal).
