This page is general health information, not medical advice. It cannot tell you whether you have an infection. A clinician can, and the testing options on this site are a good place to start.

Many people expect an infection to announce itself right away. The CDC says that is often not the case. Many sexually transmitted infections cause no symptoms at all, or only mild ones that are easy to miss. This guide shows you how to notice and record the early symptoms of STD in males, so you can give a clinician clear information.

It cannot tell you what is causing a symptom. Only a test and a clinician can do that. Everything here applies to men of any orientation and to anyone with a penis, including trans women and nonbinary people.

Why this matters in Orlando

The Florida Department of Health's FLHealthCHARTS reported a chlamydia rate of 516.7 per 100,000 people in Orange County in 2025. The statewide rate was 410.8 per 100,000. The same source lists gonorrhea at 193.7 per 100,000 in Orange County, compared with 156.5 for Florida. These are county figures. FLHealthCHARTS did not publish a city-only number for Orlando.

The takeaway is practical. These infections are common here, and noticing early changes is a useful habit.

What you will need

A private place and a few quiet minutes for a body check.
Good lighting, such as a bathroom light or your phone flashlight.
A notes app or paper to record dates and changes.
A list of your recent partners' general timing (not names). The exact dates of any new sexual contact are helpful to a clinician.
A photo ID if you plan to visit the county clinic.
A list of your medications and allergies.

Step 1: Know the most common early signs

The CDC describes several early signs in people with a penis. Having one does not mean a specific infection. Several different infections cause the same signs.

Discharge from the penis

The CDC lists discharge as a possible sign of both chlamydia and gonorrhea. It may be white, yellow, green or watery. Trichomoniasis can also cause discharge in men, though the CDC says most men with it have no symptoms.

Burning or pain when urinating

The CDC lists a burning feeling during urination as a possible sign of chlamydia, gonorrhea and trichomoniasis. Urinary tract infections can cause it too, which is one reason testing matters.

Pain or swelling in one or both testicles

The CDC notes that chlamydia and gonorrhea can sometimes cause testicular pain or swelling. This is less common than discharge or burning. Get it checked promptly, because testicular pain can have other causes that need quick attention.

Sores, blisters or bumps

Genital herpes can cause blisters or sores. The CDC says some people feel tingling or itching before they appear. Syphilis can cause a firm, round sore, usually painless, which is easy to overlook. Genital warts, linked to some types of HPV, show up as small bumps or clusters. The CDC says many people with HPV have no visible signs.

Flu-like feelings

The CDC says some people have a short, flu-like illness within a few weeks of HIV exposure. It can include fever, tiredness, sore throat and swollen glands. Many people have no early symptoms at all, so this is not a reliable way to know.

Step 2: Do a calm, private body check

Wash your hands first.
Look at the head and shaft of the penis, the foreskin if you have one, the scrotum and the groin. Note any sore, blister, bump, rash or redness.
Gently feel each testicle. Note any swelling, tenderness or lump.
Look at the tip of the penis for any fluid before and after you urinate.
Look around the anus and the inner thighs. Infections can show up there, and the CDC notes that rectal infections often cause no symptoms.
If you have had oral sex, check your mouth and throat in a mirror. Throat infections usually cause no symptoms, according to the CDC.

Keep this routine and judgment-free. A body check is information gathering, not a diagnosis.

Step 3: Write down what you notice

A short record helps a clinician a great deal. For each change, write:

What it looks or feels like, in plain words.
The date you first noticed it.
Whether it comes and goes.
The date of any new sexual contact before it started.
Any other changes, such as fever, fatigue or sore throat.

Take a photo of any visible sore or rash if you are comfortable doing so. Keep it private.

Step 4: Think about timing, including the CDC window periods

Timing affects both when symptoms appear and when a test can detect an infection. A few CDC details are worth knowing:

Syphilis: The CDC says the first sore typically appears about 3 weeks after exposure, though it can range from 10 to 90 days. It usually heals on its own, which does not mean the infection has gone.
HIV: The CDC says the window period depends on the test. A lab antigen/antibody test on a blood draw can usually detect HIV 18 to 45 days after exposure. A nucleic acid test can detect it 10 to 33 days after. Rapid antigen/antibody tests on a finger stick take 18 to 90 days. Self-tests take 23 to 90 days.
Chlamydia, gonorrhea and others: Ask the clinician about timing for your situation. Testing very soon after an exposure may need a repeat visit.

If you have had a possible HIV exposure in the past 72 hours, ask a clinician right away about post-exposure prophylaxis (PEP). The CDC says it must be started within that time frame. Miracle of Love's Test and Treat program notes the same 72-hour limit and offers low-cost PEP, PrEP and STI treatment, but check with the program on current availability.

Step 5: Choose where to get tested in Orlando

Several Orlando-area options are listed in the local testing list. A few details from the clinics' own pages:

Florida Department of Health in Orange County STD Clinic, 832 West Central Blvd, Orlando. The county page lists testing for chlamydia, gonorrhea, syphilis and HIV on a sliding scale. It says fees start at $20 and up, and payment is accepted by cash, card, Medicaid or Medicare. It is walk-in and first come, first served, and the page says to bring a picture ID. The page lists Monday to Friday, 7:30 a.m. to 4 p.m., closed 12 to 1 p.m. for lunch. Other county pages show different hours, so call 407-858-1400 before you go. The county says results take about one week.
The Center Orlando, 942 N Mills Ave. Its testing page says all sexual health testing is walk-in only. It lists HIV and hepatitis C testing at $0, syphilis at $15, chlamydia and gonorrhea at $50, and a three-test bundle at $55. STI testing is done by NPS Healthcare.
Hope and Help Center of Central Florida, 4122 Metric Dr, Winter Park. It serves the Orlando area and is not inside city limits. Its testing page says testing is free and no appointment is needed, Monday to Thursday, 8 a.m. to 4 p.m. Call (407) 645-2577 to confirm which tests are offered.
Miracle of Love, 1301 W Colonial Dr, Suite 201. HIV and STI screenings are listed Monday to Thursday and Friday morning. The organization states it does not perform swabs for gonorrhea or chlamydia and refers those to the Department of Health. Call (407) 843-1760 to schedule.

If you are under 18, Florida Statute 384.30 says a parent's consent is not required for examination or treatment for a sexually transmissible disease. The statute sets no minimum age. It also makes the fact of a minor's visit confidential, including from billing sent to a parent or guardian.

Step 6: At the visit, share your notes

Tell the clinician about your symptoms and the dates in your notes.
Say which kinds of sex you have had (oral, vaginal, anal) so they can choose the right sample sites, such as throat or rectum.
Ask which tests they are doing and which are not.
Ask how and when you will get results.
Ask what to do about sex and partners while you wait.

If a test finds a bacterial infection, a clinician prescribes treatment. Chlamydia, gonorrhea and syphilis are curable with treatment from a clinician. Trichomoniasis is also curable. HIV and herpes are not curable but are treatable and manageable, and so is HPV.

Tips and common mistakes to avoid

Waiting for symptoms. The CDC says many infections cause none. A clear body check is not a test result.
Assuming a sore that heals is gone. A syphilis sore can disappear without treatment while the infection remains, per the CDC.
Using leftover medication. Only a clinician can prescribe the right treatment for a confirmed or suspected infection.
Testing only one site. Throat and rectal infections often have no symptoms, so tell the clinician where you have had contact.
Skipping partners. Florida Statute 384.27 allows expedited partner therapy in some cases, per the CDC. Ask the clinician whether it applies to you.
Self-blame. STIs are a common health issue. Seeking care is a sensible step.
Not asking about doxy-PEP. The CDC issued 2024 guidance on doxycycline after sex for some men who have sex with men and transgender women with a recent bacterial STI. A clinician can explain whether it fits your situation.

Women may have different early signs. The site has a separate guide on STD symptoms in women that you can share with a partner.

What to expect afterward

A clinician's evaluation may help clarify what is causing a symptom. Some people find that a symptom has a non-STD cause, and others learn they have an infection that can be treated. Test results and a clinician's guidance can help you decide on next steps, such as treatment, retesting or notifying partners. Results may take days to a week.

Florida law requires clinicians and laboratories to report certain infections to the health department, including chlamydia, gonorrhea, syphilis and HIV, under Rule 64D-3.029 of the Florida Administrative Code. The Orange County health department handles surveillance for county residents.

If you notice a change, you do not have to work out what it is. Write it down, choose a clinic and ask.
