There would have to be so much semen for it to come out of the base of the condom. I'm pretty sure this did not happen. That's why they putt that tip on the end of condoms, to catch all of the sperm.
Is there any chance of pregnancy though? Or can I relax.. the condom didnt split and was fine. Even if some semen did come out the base would it get her pregnant?
Thank you :) you have calmed my nerves
The condom was most likely wet from your girlfriend. As long as you did not have a failure, like a break or tear in the condom everything should be just fine.
