So about 4 days ago me and my girl were fooling around naked and we was kissing while i was jacking off,then i proceeded to jack her off with the same hand for 2-3 minutes, she then gave me head and told me that she noticed that i had precum on my penis(not much), and now she is worried that the precum might have gotten on my fingers and there is a chance of getting her pregnant. Firstly she is a virgin,also it was her last day of period(she was finishing up that day) and I had urinated before having sexual interactions with her(a couple hours before) so that must have killed the sperms in the precum anyways right? also I am almost certain that I didnt even have any precum on my penis while i was jacking off, and even if I did I didnt feel it on my fingers..is there a chance she could get pregnant if I did have precum on my fingers? plus i didnt even go deep when i was fingering her
