question: Hi there, I had two Month ago stupidly unprotected sex. I was a bit concerned and took a tested after one month of the contact for the most common STI's , all came back negative. However 2days ago i saw a single small red bump on the top of my penis which disappeared exactly after two days. furthermore i got a flu exactly the same day i discovered the red bump. After 5 days the flu still persists however the red bump disappeared . What do you think, is it genital Herpes?Thanks
