Cervix postion question, possible TMI

So I don't check my cervix postion. I don't like the idea of my fingers introducing bacteria and what not all up in there that frequently, may be crazy but that's just me. Anyways, I am wondering if there is another way to tell what postion the cervix may be in? DH and I just did the BD and when he went in I felt some tension but what really got me thinking is how much of "him" was left on my thighs and literally falling out of me when he was done. Some usually comes out but this was a lot. I almost worry that none of it went inside because there was so much on me and coming out of me. Sorry this post turned into being pretty detailed.
