Is there any reason you have avoided testing? Not sure you need it, but it will ease your mind more than anything I could say. Syphillis and hiv can be tested with a blood test. Chlamydia and gonorrhea with swabs of potentially infected areas, in your case your penis and throat. The blood tests, from what I understand are accurate 3 months after exposure. The swabs after a few weeks. I am NOT an expert. Unfortunately either are any of the other blokes posting here. Get tested man it will ease your mind.
could you please have a look my recent question.. i am worried..
