If a condom slips off, it's not going to just slide right on: it'll just float around in your vagina, or slip out and onto whatever surface you're on. The base of the condom should be pretty snug on a guy: too snug for him to slide in and out of it like a loose sweater.
If a condom slips a bit, but is still on the penis, or slips off and the base it outside of the vagina, then there's still nothing to sweat per exposure to semen.

When it comes to things sexual, no question is silly or unnecesssary. You learn by asking.
If you can picture what might be going on in your vagina, you can pretty well answer your questions. A properly fitted condom, once in place, doesn't register much sensation to a guy, expecially once he's inside you where vaginal pressure overrides any condom pressure. So, yes, it would be possible for a guy to not know if a condom slipped off. This would be especially true if the condom split, for example, or was not properly sized or installed in the first place. But, once off, it would be essentially impossible for it to re-install itself. There is simply no way, regardless of size, how it could be held in place while the penis was inserted into it. So, if a condom comes off, you hava a potential problem.
You asked what might happen if it slipped partially off. That all depends. If any semen had worked its way down between the condom and the penis, and this area was exposed by a slipping condom, it is remotely possible that some sperm could be released into the vagina and remotely possible that such sperm could result in fertilization on an egg.
In reality, however, it usually takes a more direct and robust discharge of semen into the vaginal to result in conception.
Nature provides for this by making the ejaculation of nubile males rather powerful, strong enough to shoot anywhere from 6 inches or so to a couple of feet. This pressure is intended to force the semen into the opening of the uterus where conception can take place. The woman's orgasm also facilitates this by changing the shape of the vagina and bring the cervix in closer contact with the end of the penis. So, while any quantity of fresh semen located in or around the vagina can potentially result in conception, it usually takes a far greater quantity found in closer proximity to the cervix to result in conception.
If you are concerned, take a home pregnency test. If you test positive, see a doctor immediately. If you test negative, but you want to be more sure, purchase a second test, a different brand, and try that one. Two negatives, from two different tests should assure that all is well. Sounds like you and your bf should take a bit of time installing and checking condom before insertion. Perhaps a differnet brand might fit better. Hope this helps. Be careful.
