We had sex 2 times with my girlfriend, and after the first one I dried my penis with a paper tissue, but didn't wash my hands, some 20 minutes later I started to finger her and then we had sex again but I didn't washed my penis before and I am concerned if there is any possibility that she's pregnant. Both times we used condoms, but I am worried of the semen that could have got onto my hands. Please answer as fast as you can. Thank you in advance!
