I had a condom break during anal sex.did not notice until after i finished. he said hes negative. no cuts or blood, just broken condom. am i at risk?

At risk if...: At risk for STI if partner has STI (whether he knows or not). Also, there are billions of bacteria coming down into the anal-rectal area all day long, such as E. coli, Klebsiella and all sorts of other species. Scientists say there are more bacteria in the intestinal tract than there are human cells in our entire body (we are outnumbered). To stay safe, an anus should be reserved for just pooping.
