Me & my bf were having unprotected sex, & we always use the pull-out method which happens to be working. But this time it was different, he pulled out & while he was ejaculating I pushed him back in because i just thought he stopped. It was a lot of semen on my inner thigh & on top of my vagina, but but there was also little bit around the lips of the vagina & a little coming out of the hole. So basically what I'm asking is there a certain depth you have to be while ejaculating to get pregnant?
