Hi! So me and my boyfriend always fool around like dry humping and everything. Well, a week ago, he pulled down his pants and underwear and mine as well and kind of placed his penis in my butt like just laid it there, there was obviously no insertion of any kind.. And he didn't ejaculate hence it was only like a minute that it was there. He did it like a few times after that the following days but it was even quicker because I would push him off and say it's too risky. My period was supposed to start yesterday I never had sex could I be pregnant?
