Can I get Pregnant Like This?

Well my boyfriend recently moved in with me and the way he lives is the opposite way i like to live. For example he likes to walk around the house naked and he enjoys ejaculating everywhere. I let him do it because I want him to be comfortable, He even does it when guest are around. He says he love the feeling of ejaculating at places he please. He does it on the floor, the kitchen, the living room, the front door. But know i think i'm pregnant from being around all the sperm daily. He says im not and that if he ejaculates mor he would really like it. I just want him to stay with me and be happy.
