I’m 16 yrs old and a virgin. However, I’ve got a weird spot on my ball sac. Could I have caught an STD from somewhere like a public toilet, gym, shower…?

doctor and patient discussing testesThanks for your question. Sexually transmitted infections (STIs) are spread through contact with infected body fluids such as blood, vaginal fluids, or semen. You can get an STI through vaginal, anal, or oral sex or by sharing needles or syringes. The good news is, it’s next to impossible to get an STI from a public toilet, gym, or shower.

Many people wonder about spots on their scrotum (the sac that holds the testicles, epididymis, and spermatic cord). Spots on the skin itself can be from ingrown hairs, irritation to the skin, or dilated vessels. If you notice a weird spot, we recommend seeing a healthcare provider. They can do an exam, and let you know whether it’s normal or whether you need medicine or any other treatment.
