My friend just fingered his girlfriend while she was giving him hand job he didn't touch his penis he didn't have a proper erection but had a sort of covering over his penis head and she put this hand in her pant to locate her vagina. His finger didn't go much inside the vagina maybe a fingernail or so went and both aren't sure that they had sperms on their hands both are very scared what are the pregnancy Chances please answer ASAP.
