On July 3rd, my boyfriend and I had protected sex, but the condom was taken off after he pulled out and began to masturbate, and he was cumming, but a little bit got on the top of my vagina. It wasn't far from the opening, but I wiped it off right away & before it ran. Later, he had just wiped off a little bit of precum, waited 1-3 minutes, and then touched my vagina for a split second. I've been very nervous, I really do not want to become pregnant.
