I was recently with my girlfriend and I noticed I had precum on the tip of my penis, I did not know how long that was exoposed for. But after I noticed it I wiped it with my hand and then wiped my hand of the precum. Later I once again placed my hand in my girlfriends vagina, not to far up but still in the vagina. What I am asking is that how long does the sperm in the precum live for when exposed to air? And even after wiping my hand of the majority of the precum what are the chances of pregnancy??
Please help I am going crazy worrying about this.
