About a month ago, I got exposed. I was involve in a little romp with a girl, we didn't actually have sex but the tip of my penis touch her vagina, though I didn't penetrate but the lady was already wet so it was likely that her cum touched the tip of my penis. The whole scene lasted less than 30 seconds. Since then I have fallen ill with flu like symptoms, swollen nodes on my neck, though I have gotten better after taken antibiotics. But it still feel high temperature with no headache or cold. I would love to know if I'm at risk of contracting hiv? Should I be worried?
