Can i get pregnant if my boyfriend fingered me and later on i helped him cum with hands, i had semen on my hand, washed it with tap water and few moments later washed my vagina?

About sperm...: Sperm are so small that you can't even see one with a magnifying glass. They do not survive a good handwashing. Sperm have to be in semen and have to be put into a vagina in order for them to swim well. No worries... but life can surprise you sometimes. If not married, settled down, and ready for a surprise baby, always use reliable contraception if having sex. Also, sex is not required for teens.
