- Can you tell if someone has an STI just by looking?
Relying on visual cues alone to detect sexually transmitted infections (STIs) is highly unreliable. The only accurate way is through proper medical testing—like a blood test at a certified clinic or hospital.
That said, you can make a very rough preliminary judgment based on the following:
Smell: Some infections can cause noticeable odor. For example, a strong fishy smell might indicate bacterial vaginosis.
Appearance: Pay attention to the color, texture, and amount of discharge. Also look for any unusual bumps, sores, or skin growths on or around the genitals. It helps to get familiar with the visual signs of common STIs—seeing real reference photos can prepare you better.
Other symptoms: Pain, discomfort, fever, fatigue, and other general signs of infection should raise red flags.
But remember—many STIs have no obvious smell or visible symptoms. If something feels off, the best choice is always to see a doctor as soon as possible.
And of course, the simplest and most effective way to reduce STI risk (especially during oral or penetrative sex) is: use a condom! Always suit up properly.
- So, how do you keep oral sex clean and safe?
For the giver (the one using their mouth):
Wash your face and brush your teeth beforehand. Rinse thoroughly to make sure your mouth feels clean and fresh.
If you have any open sores, bleeding gums, ulcers, or cuts in your mouth—pause and wait until you heal. Open wounds increase the risk of transmitting infections.
If you have facial hair, consider trimming or shaving to avoid irritation and improve hygiene.
For the receiver:
Clean your genitals in advance. It’s normal for healthy genitals to have some natural secretions or scent, but hygiene is still key.
Gently separate the folds (like the labia) and rinse the area with warm water—especially in creases where fluids may collect.
If you’re self-conscious about scent, you can use a gentle intimate wash or flavored oral sex-friendly lubricant (brands like DarenTang offer these).
Avoid oral sex if you have cuts, rashes, or any open skin in your genital area.
As for pubic hair?
There’s no need to fully shave unless you prefer to—just keep things clean, trimmed, and dry, and you’re good to go.
