how long can dried sperm live

[keeks2323]

question:
if sperm is wiped off/dried up, is it still alive? also, does pre *** have sperm in it if the male has urinated a few times after previous ejaculation??
I am wondering because some of my boyfriends pre *** got on the outside of my vagina and then we had sex.  I wiped the pre *** up but i am hoping that was enough to kill it...
please answer asap and only if you know this answer for a fact. thankyou.

Precome does contain some sperm, but if this was only on the external genitalia and not actually INSIDE the vagina, it's unlikely that a pregnancy will develop. Sperm have to travel up the vagina, through the cervix, and into an unfertilized egg. That's quite a journey for a handful of little guys that never made it inside. Dry semen on things like towels and sheets will not contain live sperm. They don't survive long outside the body. Try using a spermicidal jelly in addition next time you have sex, if pregnancy is a consequence you're unable to deal with at this time. You may wish to consider discussing birth control options with your health care provider. There are many available.
(On the same note, if your boyfriend ejaculates inside you, those sperm can survive for up to 5 days).

well if your vagina was wet with juice you have the risk that the sperm went in ... the sperm stay alive about 3-5 days
