Bleeding and Fever After Anal Intercourse: Causes and Concerns

Bleeding and fever after anal intercourse?

On July 12, I had a cold with a runny nose and did not take any medication.
On July 14, I developed a fever and dizziness with a temperature of 38.0°C.
By July 16, I had improved significantly, with only a runny nose remaining.
On July 17 at 4 PM, I felt dizzy again with a temperature of 37.0°C.
After having anal intercourse for the first time, I noticed some blood on the toilet paper during my first trip to the bathroom, but it was gone by the second trip.
However, three hours after the anal intercourse, I started to have a fever reaching 39.2°C, along with dizziness and cold hands and feet.
Is this fever caused by the cold, or could it be due to an injury from the anal intercourse?

Fever is likely unrelated to anal intercourse; it is more commonly caused by a cold.
However, if anal intercourse is part of your sexual practices, it is advisable to get tested for HIV, as HIV infection can also lead to unexplained fever.

Bleeding and fever after anal intercourse can be concerning and may arise from various causes. Given your recent history of a cold and subsequent fever, it is essential to consider both the possibility of an infection related to the anal intercourse and the potential for a secondary infection due to your prior illness.

Firstly, the bleeding you experienced after anal intercourse could be attributed to several factors. Anal intercourse can sometimes cause minor trauma to the anal canal or rectal mucosa, especially if there was insufficient lubrication or if the penetration was forceful. This trauma can lead to small tears or fissures, which may result in bleeding. The presence of blood on the toilet paper after the first bowel movement could indicate such an injury. If the bleeding was minimal and stopped quickly, it might not be a cause for alarm, but it is essential to monitor for any signs of more significant bleeding or pain.

On the other hand, the fever you experienced after anal intercourse raises additional concerns. While it is possible that the fever is a continuation of your previous cold, the timing of the fever following anal intercourse suggests that it could also be related to a potential infection. Anal intercourse can introduce bacteria from the rectum into the urinary tract or other areas, leading to infections such as bacterial vaginosis, urinary tract infections (UTIs), or even sexually transmitted infections (STIs) if proper precautions are not taken. Symptoms of these infections can include fever, chills, and localized pain, which may explain your symptoms of feeling cold and dizzy.

Given that you had a fever of 39.2°C (102.0°F) after the intercourse, it is crucial to consider the possibility of an infection. Fever is the body's response to infection, and if the fever persists or worsens, it could indicate a more serious condition that requires medical attention. Additionally, if you experience any worsening symptoms, such as increased bleeding, severe abdominal pain, or changes in bowel habits, you should seek medical care promptly.

In conclusion, while the bleeding may be due to minor trauma from anal intercourse, the fever could indicate an underlying infection, possibly exacerbated by your recent cold. It is advisable to consult a healthcare professional for a thorough evaluation, especially if your symptoms persist or worsen. They may recommend tests to rule out infections and provide appropriate treatment to ensure your health and well-being. Remember, taking precautions during anal intercourse, such as using adequate lubrication and practicing safe sex, can help minimize the risk of injury and infection.
