Is there any chance that I could have

[kev664]

So im 15 male, and i had a pre-ejaculation yesterday. so i wiped it on my fingers so it was dry but then i used the keyboard and mouse, no wet semen could have gotten on the keyboard, but maybe the residue? so anyway a few hours later my sister used the computer, and im wondering if that if she touched down there could she possibly get prenant? how can i be sure? im like freaking out over probably nothing, and im not even certain that she did, but help me?

It's extremely unlikely. Don't even worry about it. I think sperm die after about 20 min tops in the wrong conditions, as in not moist areas similar to that of a woman's vagina. Plus pre-ejaculation doesn't have that much sperm, so don't stress. Nothing happened or will happen.

Im gonna go with no. There are very few sperm in preejaculation plus hours outside the body isnt good for sperm survival. I think you are in the clear
