I am one of those women that does it all the way through :redface:
I think it is a part of my sometimes extreme submissive side, that I love to have my husband in my blood. There is some kind of sex-magic in that, I don't really know how to explain it but it is very powerful for me. Maybe I associate it subconsciously with when I lost my virginity to him, as that was a brutal, bloody, mess. I don't know for sure, but it is very emotional for me.
