If you have an std what should you do other then talk to a doctor?

If you do not want to talk to a doctor about it then I suggest you avoid sexual contact with others.

Part of becoming a responsible sexual being is routinely having a doctor screen for STI's. It's not an embarrassing thing at all. You are protecting yourself as well as your partners from becoming infected. Don't worry, there is nothing you can tell a doctor that they haven't heard before at least several times. Trust me...
