About three weeks ago my friend and I got rather intimate. He fingered me and I sucked him off he came on my face and I wiped it off with my hand... I got changed and went to the bathroom. However, I forgot that I had wiped the sperm away with my hands and then proceeded to wipe my vagina with toilet paper after using the bathroom. ( I apologise if this is too much information I'm just really paranoid that I am pregnant) I washed my hands before leaving the bathroom and a few hours later we repeated the previous events. We did not have sex and his penis was no where near my vagina however whilst I was sucking his penis, he masturbated himself and I know that precum may have been on his hands. Would that precum have died within the space of a few hours? Also could forgetting to was my hands before I went to the bathroom mean that sperm would have got into my vagina? Could I be pregnant? Please help me I am so afraid. I am due my period next week and I am so afraid.
