Is there any danger in not using a condom if the guy doesn't cum?

It's very risky and very dangerous and any other words you can think of too. Like other girls answered here it only takes one sperm to find its target. There most usually always is some precum when a guy is hard even if it's just a tiny bit that you hardly notice. Cumming has nothing to do with it. Condoms are for preventing getting pregnant and from getting any STDs. If you don't use them when having sex you stand the chance of getting both whether or not he cums.

There is a possibility that you can get pregnant. All it takes is one sperm to get to an egg to fertilize it. You can even get pregnant if he cums on you and some of the fluid gets inside you. You should always use a condom because accidents do happen and its better to be safe than sorry.

Maybe my boyfriend is just infertile, but we've been doing the pull out thing for 3 years now, having frequent sex, and not a thing has happened. (He might just be really good at telling when to pull out) Unless you really trust that he knows his own penis and can pull out BEFORE the precum, make him use a condom!

I got pregnant this way, so yes! The fluid can always have some sperm in it.

Yeah, it is dangerous because you could get pregnant due to pre-cum, in other words, even before he ejaculates a little bit does come out and there is sperm in it. So even if he pulls, there are risks.

I think you definitely should use a condom, even if he pulls out before he cums, there's still a chance (or risk) that just a little little bit came before that, without him noticing. Two of my brothers accidentally knocked up their girlfriends like this. Maybe you should consider pills instead?
