Is it all supposed to leak out??

I had a hysterosalpingogram done today and the doctor had so much trouble finding my cervix bc it's sooo far back and low and right tilted. Which made me think, could it be that the semen just isn't making it to my cervix? Cuz if you just go straight ahead you reach a vaginal wall/dead end. So maybe when DH cums it just hits the wall. 
Now my question is, after BD is most of the semen supposed to come out? Everytime we have sex, as soon as I stand up, all of the semen leaks out! Is that normal or could it just be that he's cuming nowhere near my cervix and nothing gets absorbed. I have no one else to ask questions like that so thanks in advance for any answers.
