what are the percentages of getting an std for unprotected sex?

i had unprotected sex with a girl about a week ago. i dont know if she has an std but found out later she sleeps around. all time together we had sex for about an hour. what are my chances of getting any std from that? like possible percentages of each std? thank you.

Well you were told from a friend that she sleeps around a lot right? Rumors are often untrue. And even if she does how do you know that she is not having protected sex and with you it was just this one occasion and now she is scared that she got something from you?

You can tell if someone has something so the best thing you can do it test. If she does have something there is no guarantee that it was passed to you but the risk would be high since you did not use a condom.
