What is that mark that has just appeared on your genitals? Is it a pimple or is it a sexually transmitted disease? Sometimes it's hard to tell what's normal and what you need to be concerned about. The symptoms of STDs are incredibly varied, and not everyone with the same infection will have the same signs.

Asymptomatic STDs: The Hidden Epidemic
Perhaps you've heard someone say, "I don't need to get tested for STDs. I'd know if I had one." Perhaps that someone was you. Unfortunately, it simply isn't true -- the vast majority of people with sexually transmitted diseases never know they have them until it's too late. What is too late? It varies for different people. Too late could be when you try to have a child and discover that untreated chlamydia has rendered you infertile, or it could simply be hearing that you've passed on a disease to someone you love.
