Physiologically, there is NO connection between your anus/colon and your reproductive system, however as Tish said, if the semen comes out of you, and gets to your vagina, yes, you can. He should be wearing a condom anyway, for his own protection. There are lots of unfriendly bacteria in your colon.
There are virgins who have gotten pregnant from semen getting near their vagina. Anything is possible.
For the most part no. However it would be dependent on if any of the seamen leeked into your vagina with sperm. Statistically I would have to say it is low.
