My penis is a bit sore after oral sex. Is this serious?

Question

Hello doctor,

I would kindly ask for help as I am on vacation and currently do not have access to a doctor.

Yesterday, I had oral sex (the partner performed a blowjob). She has purulent tonsillitis but is on antibiotics, and it has been a little over 72 hours since she started treatment. After that, we had regular intercourse.

This morning, I noticed something on the tip of my penis. The sexual activity occurred with her underwear on, meaning I did not have direct genital contact with her.

There is mild stinging, but I do not have a fever or other symptoms. I immediately washed the area after intercourse.

We have been exclusively monogamous for the past five years, and this was our first sexual encounter with each other.

Do I have a reason to be concerned?

Please help.

Hello,

Welcome to icliniq.com.

Thank you for reaching out and explaining your situation in detail. I understand how concerning it can be to notice a new change on the penis, especially while you are on vacation and unable to see a doctor in person.

I will address your concern clearly and calmly to help reduce your anxiety. Based on your history, the timing of symptoms, and the appearance in the image (attachment removed to protect the patient's identity), this seems to be a mild local irritation rather than a serious infection.

Small red spots and superficial changes on the penile skin, along with only mild stinging and no fever or discharge, commonly occur after friction or minor trauma during oral sex.

Oral contact can cause tiny, often unnoticed micro-abrasions due to suction, dryness, or accidental tooth contact, which may become visible the next day as redness or mild soreness.

Regarding your partner’s purulent tonsillitis, it is important to note that tonsillitis is not a sexually transmitted infection. Additionally, after more than 72 hours of appropriate antibiotic therapy, the bacterial load is significantly reduced, making transmission unlikely.

The chance of developing a penile infection, especially without pus, swelling, fever, or significant pain, is very low.

Given your exclusive sexual relationship for the past five years and the absence of classic STI (sexually transmitted infection) signs, a sexually transmitted infection is highly unlikely.

Please keep the area clean and dry, wash gently once daily with plain water or a mild, fragrance-free cleanser, and avoid sexual activity for a few days to allow healing.

Do not apply harsh antiseptics, alcohol, or unnecessary antibiotic creams, as these can further irritate the skin. You may apply petroleum jelly to the affected area to soothe it.

Seek medical evaluation if the area does not improve within five to seven days, becomes more painful, develops discharge, blisters, or ulcers, or if you experience fever or burning during urination.

Overall, there is no immediate reason to panic. This appears to be a minor, self-limiting irritation that should settle with simple care and a bit of time.

I hope this answers your questions. Please follow up if you need further guidance.

Thank you.
