Red Rash After First Sexual Experience: Is It Inflammation or STD?

The first sexual intercourse was protected with a condom, but there is a rash?

Hello, doctor.
I had sexual intercourse with my first girlfriend, and we both confirmed that it was our first time.
We used a condom properly from the beginning to the end, and I checked afterward to ensure that the condom did not break (I performed a water test).
The next day, I noticed a small red bump near the frenulum on the dorsal side of my penis.
It is slightly raised but almost flat, and it feels a bit different, although it is smaller than the pearly penile papules I previously had checked.
The color is a reddish hue, similar to that of deeper skin tissue.
It is not painful or itchy, and there are no unusual sensations when urinating.
Could this be inflammation or a sexually transmitted infection? I am very worried it might be an STI! The day after, when I got home, I retracted my foreskin to examine it.
I used antibacterial hand soap to wash my hands before touching it.
Is this safer? I wanted to check if the red bump was raised, and I was concerned about coming into contact with bacteria or viruses, so I washed my hands before touching it.
Please help clarify my concerns.
Thank you.

More Info

It's understandable to feel anxious after experiencing any unusual symptoms following a sexual encounter, especially if it's your first time. The appearance of a red rash on the penis can be concerning, and it's important to consider various factors to determine whether it might be an inflammation or a sexually transmitted disease (STD).

From your description, it seems that you and your partner took precautions by using a condom throughout the sexual experience, which significantly reduces the risk of transmitting most STDs, including HIV. Since you confirmed that the condom did not break, the likelihood of contracting an STD from this encounter is lower. However, it's important to note that some STDs can be transmitted through skin-to-skin contact, particularly herpes and human papillomavirus (HPV), which can be present in areas not covered by a condom.

The red rash you observed could be due to several reasons. It might be a mild irritation or inflammation caused by friction during intercourse, especially if it was your first time. This type of irritation is common and usually resolves on its own. The fact that the rash is not painful or itchy and that you do not have any other symptoms, such as discharge or pain during urination, is a positive sign.
Another possibility is that the rash could be related to a condition known as pearly penile papules, which you mentioned you have previously been diagnosed with. These are harmless and common anatomical variations that appear as small, dome-shaped bumps around the corona of the glans. If the new rash is smaller and different in appearance compared to your previous papules, it might still be a benign condition.

Regarding your concern about hygiene, washing your hands with antibacterial soap before touching the area is a good practice. It helps minimize the risk of introducing any bacteria or irritants to the sensitive skin of the genital area. However, it's essential to avoid excessive manipulation of the area, as this can lead to further irritation.

If the rash persists, changes in appearance, or if you develop additional symptoms such as pain, itching, or discharge, it would be advisable to consult a healthcare professional for a thorough examination. They may recommend tests to rule out STDs or other conditions, depending on your symptoms and sexual history.

In summary, while the appearance of a red rash after your first sexual experience can be alarming, it is not necessarily indicative of an STD, especially given the precautions you took. Monitoring the rash for any changes and seeking medical advice if it does not improve or worsens is the best course of action. Remember, open communication with your partner about sexual health and regular check-ups are key components of maintaining sexual health.
