What are the chances of pregnancy in this situation? (NSFW).

Asked by robotmonkeyarm (151) November 18th, 2012 from iPhone

So basically this girl was over at my house and we were fooling around.

She had taken all her clothes off and I was down to my boxers. We grinded just slightly, but I didn’t want to risk coming near ejaculation, so I pushed off (was very intimate). After a while I started fingering her and this is where I start to worry. Though I didn’t ejaculate during this time I am almost positive I had some pre-cum and I am worried that it could have soaked through my boxers and onto her vagina at some point. I never made contact with my penis directly, but I “adjusted” myself a few times, is there a chance it could have gotten on my fingers while adjusting my boxers and gotten inside her while fingering?

I have heard that sperm dies immediately upon contact with air, but I’m still a nervous wreck right now, as she’s not on any birth control and I wasn’t wearing a condom as I had my boxers on and never ejaculated. From what I have read, it seems like if she were to get pregnant from this it would be a very unlikely thing, but I would like to know from some more experienced flutherers what the actual chances of a pregnancy here are in this exact situation.
