Yes, it does sound like you have had a pregnancy risk. If semen got on your vulva, and it sounds like it did, you've had one.
Has it been 5 days or less since this happened? If so, you can still get emergency contraception, it's just that it works best within 3 days. See this page for more: Emergency Contraception .
You need to wait till 10-14 days after the event occurs to take a pregnancy test, or the first day of a missed period, so you can't take one yet.
In the future, whenever something like this is going on, there should be a condom on that penis so that you don't have to worry about this sort of thing. Check out these pages for more:
