10 Signs of an STD in Men
Many people aren’t familiar with the symptoms of an STD in men. In fact, some of the signs may surprise you. Here’s a quick and easy checklist if you aren’t sure!
1. Discomfort or burning sensation after urination
2. Discharge from the penis
3. More frequent urination
4. Testicular pain, tenderness and inflammation
This might just be a sign you need to give your equipment a break. However, this symptom can also accompany a variety of STDs.
5. Itching inside the penis
This symptom is common to trichomoniasis, as well as yeast infections in men.
6. Anal discharge, bleeding, pain or itching
7. Discomfort during intercourse or a burning sensation when ejaculating
If you’re experiencing some unpleasantness when doing the deed (or as you’re crossing the finish line), this could indicate an infection.
8. Sore throat
This one surprises many people and is often dismissed as a cold or flu symptom. Don’t just buy some lozenges and shrug off that sore throat if you’re experiencing this symptom within days of going down on your partner.
9. Fatigue, sore muscles and joints, fever, swollen lymph nodes
This sounds like the aches and pains that come with the flu, but these are also signs of Hepatitis C or HIV.
10. Blisters, warts, sores around the penis, groin and rectum
The absence of evidence isn’t evidence of absence
It’s important to remember that sometimes the signs of an STD in men can be very mild. You may not experience any symptoms at all. It’s important to know what to look for, as well as the incubation and testing timeframes for the most common STDs. If you’re sexually active, with or without symptoms, it’s time to get tested.
