Hello all, I recently made a stupid mistake in the Philippines. Had roughly 20 secs of unprotected sex with a sex worker in the philippines. I was drunk and stopped after I realized the severity of the situation. The next morning I was very scared and freaking out. I went to a nearby clinic and told the doctor that a condom broke during sex with a local sex worker. He mentioned a prophylaxis and antibiotics. I was worried about HIV and thought that this prophylaxis was for aids. He gave me a shot and a 10 day supply of doxicycline (antibiotic). After, I realized that this was for the prevention of an STD. I have searched the internet and have not found anything about STD prophylaxis. I am now concerned/wondering what Shot I was given. Has anybody heard of this type of treatment??
