Well, orally, most stds don't cause symptoms. Oral herpes usually presents with sores on or just in the mouth. Syphilis will give you a sore at the point of infection.
Genitally, you could get a discharge, burning with urination, itching. Herpes would probably cause sores or blisters, or even rough patches. Syphilis will cause a sore in its first stage.

Thanks AJ. what symptoms are considered to be STD? or herpes?
I don't know what this is, but its not an std. You should post in the dental forum. It fits no patterns of an std.
And really - go to your doctor.
