I had a protected encounter with a lady but I was unsure of her status. I used the same condom for oral sex and then intercourse. About two weeks later I got two huge pimples, one in the middle of my chest and one below the pectoral muscle. They healed in about two weeks but left blemishes. I then started to break out with acne bumps on my stomach, shoulders and a couple on my stomach. They all healed but left blemishes. I have a small lymph node on my underarm. I haven t had any other symptoms of flu, sore throat, weakness, etc. Could i have HIV exposure
