I feel awfully embarrassed about this situation but I do really need the facts. So my period ended a week ago and I have a cycle of like 45 days+ (long I know). Anyway, so today I gave my boyfriend a handjob. He got Semen on his hands. He claimed to have washed his hands after but I'm not sure if he did. About an hour or so later he touched my vulva and vaginal opening etc with the same hand but didn't go Inside the vagina. I'm worried that some sperms could have survived from when he got it on his hands an hour before. Also after that he ejaculated a second time in his pants and about 10 minutes after that I layed on top of him while fully clothed but while he still had the semen in his boxers and pants. Could the sperm have gone through? Also I witnessed him touch the wet boxers and about 10 minutes later he touched my pubic area (his hands were dry). Could the sperm cells travel across skin?
