My bf ejaculated in his underwear. He was unable to change clothes at the time. He walked home and cleaned himself up and changed his underwear (this was about 30 mins later) the semen was still wet when he was changing his clothes and his hands came in contact with it. After this he put his fingers on my vaginal opening (they were dry) and I'm just scared that there could have been traces of sperm on his hand from when he was cleaning himself up. Also before he changed his wet semen boxers I sat on his crotch area while only wearing lace panties. It didn't Seem to have leaked through but I'm still concerned. Also a bit after I gave my bf a hand job and got semen on my hand whiteout realising and uses the hand with semen on to pull up my jeans. I'm really scared. Do I have any chance of becoming pregnant?
