My boyfriend and i were laying down fully clothed when he asked me to give him a handjob..When i did he came and it got all over my arm and my chest/shirt..After this was done when i got up i had to pull my thong down because it had riden up.. if sperm was on my fingers is it possible to get pregnant from that?

I am a virgin i have not had sex and the penus never neared my vagina.

Please help
