Could my foreskin blisters after sex indicate STI?

Hello,

Welcome to icliniq.com.

I read your query and understood your concern.

It can be some sort of sexually transmitted disease (STD). You need to upload a photo of the blisters if you have one.

1. Were the blisters painful or burning?

2. Any flu-like symptoms, body aches, or groin lymph nodes?

3. Was the partner’s status known, or did the partner have oral lesions?

Blisters appearing on the foreskin about six days after being with a new partner are not usually due to simple balanoposthitis. The timing and appearance can sometimes happen with a viral infection like herpes, even if the blisters heal quickly. Do not worry, many people have mild symptoms, and it is manageable. But it is important to confirm the cause.

My suggestion:

1. Get a herpes simplex virus (HSV) blood test, immunoglobulin G (IgG), now, and we will repeat it after a few weeks if needed. It is also advisable to do a basic sexually transmitted infection (STI) screen since you have a new partner.

2. Avoid sexual activity until we know the cause, just to be safe. If the blisters come back, you need to get a swab test done.

Lastly, if you can convince your partner to have an STD profile check test, then it will be helpful (only if she understands).

I hope that this answers your query.

Kindly follow up if you have more doubts.

Thank you.

Hello,

Welcome back to icliniq.com.

I read your query and understood your concern.

Thanks for sending the photos. The small bumps you had look like tiny fluid-filled blisters. Since they appeared about six days after being with a new partner and went away quickly after popping, we cannot say for sure what they are just by the picture, but this pattern can sometimes happen with early herpes or with simple irritation or infection of the foreskin.

The good aspect is that there is no ulcer, no spreading, and no pain, all of which are good signs. Many harmless conditions can also look similar.

But to be safe, here is what I recommend:

1. Do a herpes simplex virus (HSV) blood test, immunoglobulin G (IgG), now. If it is negative, we repeat it in six to eight weeks to be sure.

2. Do a basic sexually transmitted infection (STI) screen since this was a new partner.

3. If you get any new blisters, do not pop them, so you can get a swab test (that test gives the most accurate diagnosis).

4. Avoid sex until the skin is fully healed.

Right now, nothing seems alarming, but we need to rule out herpes properly and keep an eye on it. I am not recommending any medications as of now, as we will consider them only if we have a proper diagnosis or recurrence of the lesion.

I hope that this answers your query.

Kindly follow up if you have more doubts.

Thank you.
