I am a 35 yo old male who had sex with a girl, and a condom was used. After pulling out I noticed the condom was hanging out of her vagina. I believe I may have been exposed for 5 minutes unprotected. I completed an hiv test and it was negative,l. I'm nervous about gonorrhea, chylmydia, and syphilis. This incident occured 70 days ago. My question is by now would I have developed symptoms now? How long can I have these diseases with any symptoms?
