okay me and my boyfriend had protected sex, then we waited thirty minutes and had sex again but for the first two minutes of the second time he didn't have a condom on, and then he put one on..could i get pregnant? what are the chances?
Yes, you could get pregnant by doing this. Your boyfriend already had sperm in his penis from the first time. Even if you wait awhile after a second time or more you have to use a condom every single time to prevent an unplanned pregnancy.
