There a incident happened with me and my gf. We two were having good time. There was sperm on my hand for more than 5 minutes. And after that I washed it with normal tap water .and after 10-15 min I fingered my gf. But my hand has no sperm fluid but I worry if there was any sperm cell which can make her pregnant. Although she had her period on 2nd dec and incident took place in 8 dec she has a cycle of 25 to 28 day no sex act was done. I am so much tensed about this situation. There was no semen I washed it but then also I am getting tensed.
