Chlamydia and gonorrhea - You can test now
Syphilis - 6 weeks after exposure
Remember that most people don't have STD's and most singles exposures don't transmit them.
Hi, if you donot have any white puss discharge from your penis or any burning when urinating that happen at the 5 day mark, you can pretty much rule out the more common std,s like Gono and Chlamydia.Testing would not be recommended when no symptoms are present unless you have a long term partner. The more common std,s would be a simple UTI. You know your body and if you feel something not quite right then see a doctor and can run some urine and swab tests.
