So the other night I gave this guy head and he finished and I swallowed and none of it got anywhere. Then about four hours later we kind of tried having sex (my first time). We didn't use a condom but I'm not totally sure you can call it sex. He couldn't really get it in, maybe like an inch in but I'm just wondering if I should be worried about if all the sperm was off of him or if I should be worried about getting pregnant
