If a guy had semen on his hands and wiped it off with a tissue but did not wash his hands and then fingered his girlfriend could she get pregnant?

no she couldn't be pregnant as the sperm would have died anyway, as it was in the air...

sperm does not die just because it hits air...however if he wiped it all off and his fingers were dry i would say its not a possibility...but if a guy jerks off and has semen on him and then inserts it into you...you can become pregnant...the semen does not just die in the air...if it did in vitro would never work because the mans sperm would die as soon as it landed in the cup
