Regarding penile issues?


I recently noticed a bump on my penis that looks like a pimple.
It feels slightly painful when I press on it and is red in color.
Upon closer inspection, I can see that it is located at the base of a hair follicle.
I'm not sure what this symptom could be.
Additionally, what is considered a normal length for the penis?

Just squeeze it out with your hand, and it will be fine!

When it comes to penile bumps, it’s important to understand that they can arise from a variety of causes, and not all of them are indicative of a serious condition. Based on your description of a bump resembling a pimple, which is tender to the touch and located at the base of a hair follicle, there are several potential explanations.

One common cause of such bumps is folliculitis, which is an inflammation of the hair follicles. This condition can occur due to bacterial infection, irritation, or blockage of the follicles. Folliculitis typically presents as small red or white bumps that may be itchy or painful. If the bump is indeed folliculitis, it may resolve on its own or with the application of topical antibiotics or antiseptics.

Another possibility is a sebaceous cyst, which is a non-cancerous lump beneath the skin that can occur when a sebaceous gland becomes blocked. These cysts can sometimes become inflamed or infected, leading to tenderness and redness. They are usually painless unless infected.

Genital warts, caused by the human papillomavirus (HPV), can also appear as small bumps on the genital area. These warts can vary in size and may be flesh-colored or slightly darker. If you suspect that the bump could be a wart, it’s advisable to consult a healthcare provider for an accurate diagnosis and potential treatment options.

In terms of normal penile size, studies indicate that the average erect penis size is approximately 5 to 6 inches in length, while the average flaccid size is around 3 to 4 inches. However, it’s crucial to remember that there is a wide range of normal sizes, and individual variations are common. Factors such as genetics, hormonal levels, and overall health can influence size.

If the bump persists, increases in size, or is accompanied by other symptoms such as discharge, significant pain, or changes in skin color, it is essential to seek medical attention. A healthcare provider can perform a physical examination and may recommend further testing or treatment based on the findings.

In summary, the bump you are experiencing could be due to several benign conditions such as folliculitis, a sebaceous cyst, or potentially genital warts. It’s essential to monitor the bump for any changes and consult a healthcare professional if you have concerns. Regular self-examinations and awareness of your body can help in identifying any unusual changes early on, leading to timely medical intervention if necessary.
