“Bleeding after sex is not normal and should always be evaluated,”  – Dr. Natalya Danilyants

In this Bustle article, Dr. Natalya Danilyants explores the potential causes for bleeding after intercourse. These can include sexually transmitted infections (STIs), uterine polyps, or in more serious cases, uterine or cervical cancer. While uterine and cervical cancer are more rare, women who experience post-coital bleeding should see a physician to determine the cause.

FROM THE ARTICLE:

While we don’t talk about it in sex ed class for some reason, bleeding during or after sex (particularly penis-in-vagina penetrative sex) is relatively common. Your vagina, while a total badass that can squeeze out a tiny human all by itself, is also made of pretty tender material. It’s sensitive up in there, which is a big part of why it feels so good to have sex. But it also means that when it’s banged around, there can be a bit of blood. Your vaginal canal is also connected to a bunch of other delicate and complex areas, and disruption of those can result in some bleeding.
