Why You May Bleed After Sex


Postcoital bleeding (after sex) can be alarming. This type of bleeding is not related to your menstrual cycle. and the amount of bleeding after sex can range from a small amount of spots to a heavy, bright red puddle soaked in sheets. Anatomically, the two parts of your body that can bleed from friction or a relative vaginal sex injury are your vagina and the neck uteras.

Postcoital bleeding refers to bleeding that occurs after the types of sex that involve vaginal penetration. This means that postcoital bleeding can occur after penetration into the vagina of the penis, dildo or finger of the partner.

If you have postcoital bleeding, you may also experience abnormal uterine bleeding unrelated to sex. Approximately 30 percent of women who bleed during sex also experience other episodes of abnormal bleeding beyond their normal monthly period. 

Postcoital bleeding is usually painless. Only about 15 percent of women with bleeding after sex will also complain of pain during sex, called dyspareunia.

It is important to see your health care provider if you have postcoital bleeding.

Vaginal causes of bleeding

When your vagina bleeds after sex, it is more likely the result of a direct injury to the wall of your vagina. this is called a vaginal rupture and the bleeding is bright red and can be quite intense.

In general, the vagina does not break during sex. If the vagina is not enough grease. friction caused by penetration into the vagina can cause the vaginal wall to break. You may experience insufficient vaginal lubrication if any of the following occurs:

  • Vaginal penetration occurs before you are excited enough to self-lubricate.
  • You have low estrogen levels. It occurs during breastfeeding and during menopause.
  • You have had unusually rough sex or used a foreign object for vaginal penetration. This includes if your partner has genital piercing or implants like metal bars.
  • Some skin diseases or medicines may also increase the chance of tears during sex.

Although not common, vaginal tears are often the cause of postcoital bleeding, which is strong enough to take a woman to the emergency room after sex.

The vagina has a rich supply of blood and these types of lacerations bleed a lot. This usually means that stitches or stitches are required to stop the bleeding. Sometimes it even means a trip to the O. R.

Causes of cervical bleeding uteras

Unlike the vagina, bleeding from the cervix uteras after sex, it’s usually not strong enough to take you to the emergency room in the middle of the night. There is usually a limited amount of bright red blood. It can be so minimal that you only notice it when you clean or change the sheets.

Even if it may be minimal, it is important to discuss any bleeding after having sex with your health care provider. Basically, there are four reasons why your cervix may bleed after sex.

Cervical ectropion uteras

The cervix consists of two areas and two types of cells. The outside of the cervix contains the same type of cells as the vagina, but the inside or canal of the cervix contains a different type of cells.

The cells that cover the cervix act as a barrier and are resistant to the vaginal environment, including friction during sex. However, the cells lining the cervical canal are much more fragile.

Cervical ectropion describes a condition or anatomical change in which the cervical canal is turned upside down, exposing these more fragile cells to the vaginal environment. Birth control pill use and pregnancy may be associated with these changes.

These cells bleed very easily even with a slight touch. If you have this cervical variation, you are more likely to have postcoital bleeding.

Cervical Polyps uteras

Cells lining the cervical canal can also form polyps. Endocervical polyps are usually benign neoplasms. Because they have such a rich supply of blood, they bleed easily.

These polyps develop in the cervical canal, but as they grow, they protrude from the end of the cervix, putting them in an ideal position for irritation and bleeding during sex.


Inflammation of the cervix called cervicitis can also cause bleeding after sex. Chlamydia it is the most common cause of acute cervicitis.

In the early stages, chlamydia infection has no real symptoms, but it is a serious sexually transmitted infection that can affect your fertility. However, it is easy to treat with antibiotics.

Cervical cancer

This is by far the most serious cause of postcoital bleeding. However, it is also the least likely cause. This is especially true if you have seen your health care provider for a regular cervical cancer exam

Cervical cancer may be one of the first things you’ll find in an Internet search about postcoital bleeding. But there are other potential causes of your postcoital bleeding, and it is not necessary to assume that it is cervical cancer. However, it is important to discuss postcoital bleeding or any other problems you have with your health care provider.


To help your healthcare provider determine the cause of your bleeding, think about how you would answer the following questions:

  • You have a new sex partner?
  • When did the bleeding begin?
  • Do you practice safe sex?
  • Do you use sex toys or other foreign objects during sex?
  • Does sex hurt?
  • Do you always bleed after sex or only at certain times of the month or in certain poses?
  • Do you have bleeding outside your usual period that is not related to sex?

You may feel uncomfortable or uncomfortable talking about bleeding after having sex with your health care provider, but your sexual health is an important part of your overall health and it is very important for you to ask this question, even if your health care provider forgets to ask. And if your health care provider doesn’t make it easy for you to talk, you may want to consider finding a new one.
