White spots at the base of pubic hair?


Hello doctor, a few days ago I had sexual intercourse with a sex worker...
it was unprotected oral sex, followed by protected vaginal intercourse.
I'm not sure what the chances of contracting an STI are in this situation.
Additionally, I recently noticed distinct white spots at the base of the pubic hair near the penis, while the hair further away does not have these spots.
Could this be a sign of an STI?

If you are worried about winning a prize: Congratulations, you may have won a prize in the form of pubic lice or head lice, which are small parasites.
You can use a strong flashlight along with a magnifying glass to take a closer look, and then search for images on Google for confirmation.
They typically reside at the base of the hair in the pubic area or on the scalp, close to the skin.
For treatment, the simplest method is to shave all pubic hair completely and then gently scrub the hair follicles with soap daily to remove any remaining parasite eggs.
If you are still concerned, you can visit a dermatologist or urologist for appropriate medication treatment.

More Info


When it comes to concerns about white spots at the base of pubic hair, especially following sexual encounters, it's essential to approach the situation with caution and awareness. The presence of white spots can be attributed to several factors, and while sexually transmitted infections (STIs) are a valid concern, they are not the only possible explanation.

Firstly, the white spots you are observing could be a result of several benign conditions. One common cause is the presence of sebaceous glands, which can appear as small white bumps at the hair follicles. These are typically harmless and are a normal part of skin anatomy. Another possibility is folliculitis, which is the inflammation of hair follicles, often caused by bacteria or irritation. This can lead to small, white, pus-filled bumps that may resemble spots.

However, given your recent sexual activity, it is prudent to consider the possibility of STIs. Certain infections, such as genital warts caused by the human papillomavirus (HPV) or molluscum contagiosum, can present with similar symptoms. These conditions may lead to the development of small, raised bumps in the genital area. Additionally, some STIs can cause changes in the skin or mucous membranes, including lesions or spots.

Regarding your question about the risk of contracting an STI from unprotected oral sex followed by protected vaginal intercourse, it is important to note that while using a condom significantly reduces the risk of transmission for many STIs, it does not eliminate it entirely. Oral sex can still pose a risk for infections such as herpes, gonorrhea, or syphilis, especially if there are cuts or sores in the mouth or throat.

If you are experiencing any discomfort, itching, or changes in your genital area, or if the white spots persist or worsen, it is crucial to seek medical attention. A healthcare provider can perform a thorough examination, possibly including tests for STIs, to determine the cause of your symptoms. Early diagnosis and treatment are vital for managing any potential infections and preventing complications.

In summary, while the white spots at the base of your pubic hair could be benign, given your recent sexual activity, it is wise to consult a healthcare professional for a proper evaluation. They can provide you with the necessary information and treatment options based on a comprehensive assessment of your symptoms and sexual history. Remember, open communication with your healthcare provider about your sexual health is essential for your well-being.
