I and other volunteers see a lot of posts regarding symptoms after an exposure. Some are minor such as a rash or a swollen node to "HIV like" such as a cluster of fever, sore throat, sores and body aches. Keep this in mind that as humans we are covered or exposed to germs, common viruses, and fungus which we all carry. This is called the "the biome" which is the invisible part of our environment. When we have sexual contact with somebody or their body fluids we expose each other to these organisms and our body reacts accordingly to fend off these invaders sometimes making us feel ill or display manifestations of symptoms. Stress and anxiety post exposure contribute to this since chronic stress decreases the immune system and makes us more susceptible to common infections. But what about the rashes? One may ask. Stress and anxiety causes the "fight or flight" response in our bodies causing release of cortisol which causes itchy rashes on the skin. Cortisol rashes are also called "hives" can be be similar to rashes found in STDs and can be frightening when they occur, (Ive been there). Allergic reactions also play a part. Also, sometimes the timing of exposure and illness is purely coincedental. Finally, if you have had a high risk exposure- when in doubt, test out. Hope this helps anyone.
