About 5 weeks ago my roommate and I received oral sex from the same two girls. He was infected with chlamydia, but had been on antibiotics for 7 days. About a week and a half ago I had sex with a different girl unprotected. I started showing symptoms of chlamydia three days ago and went to get treated for it two days ago. I need to figure out the source of the infection, I am leading towards it being the last girl I had sex with, but am unsure. Is 5 weeks too long to show symptoms of chlamydia? I am a male.
