Dumb but confused post lol * anal

So my bf and I did anal and he came in me. After I went to lay down in bed for a bit bc I was just super tired from a long day and so one. I rested for about and 1 and 30 minutes and then he went at it again with me. He started to do anal again and then he put it in my vag hole ( yes ik that is bad and can cause infection, I was a bit upset) do you think that the semen might’ve transferred onto him when we did anal and then yeah, transfer into my bag hole bc he stuck it in tthere after ? I might just be paranoid but again it is something I would want to know 🤔
