Only the head of your penis needs to be protected so when you pulled out was the head still protected inside the condom that was stuck inside her? What kind of test did you do?
You are getting a little over the top. First, if your penis was exposed, you STILL had a very low risk as a one time exposure is low risk. You are about at the 1% range. Second, your penis may have been covered inside and only looked uncovered when you pulled out. Between those two things, you have to get control of your anxiety. You can ask for a 4th generation DUO test and you'd have a conclusive answer today. There has to be clinics or doctors near you that you can get that test. you may have already had it. CALL and ask what test you took. Worrying for nothing solves nothing. AND, doctors do NOT use symptoms to diagnose symptoms. Only a test. So, find out what test you took, realize your risk is low and keep your head together about this!
