So I have really bad health anxiety. I haven't had sex since 2018 and have only had sex about 3 times each lasting roughly 3 or 4 minutes due to slipping out as me and my ex were both bigger people. A condom was used everytime. No breaking only one slip but it was when I was all the way out the condom slipped. We were both virgins (so she said) I know not everyone is honest and I was in a pretty abusive relationship so idk what to really believe. The relationship was monogamous and long term and I have no reason to suspect infidelity. So my anxiety stems from "what if I caught something and didn't know it" think like HIV or some other silent type disease. I googled it and read about symptoms and came upon seroconversion and shit and that freaked me out because a couple weeks after that I counter we both became sick with the flu 100% tested confirmed flu we got it from her niece who had the flu and we were watching her so I know 100% it was the flu. But irrational anxious ridden mind. I haven't been with anyone since then there was sex those few times with a condom and oral and hand stuff mostly oral with a condom due to her preference due to apparently my foreskin getting in the way? Idk we were both inexperienced. So like I said the chances of even that partner having anything are basically zero if anything is to be believed. Is my fear based in reality or is I just overactive anxiety? I know a test would ease my mind but that's not on the table right now though I don't plan to be with anyone as I'm working on myself and have been since that relationship and only plan to do sexual stuff with someone I'm committed to (due to having such anxiety) and would definitely take a test just to make my partner feel at ease.
