Hi Doctor, I experience a slight discomfort on my penile head. Also, urine flow has been relatively weak, and interrupted. I am 23 years old, no other health issues. This occured soon after the week when I was abit sick, with heatiness and flu symptoms . I had 1 sex session during several days before this occured. However, it was a regular session, and not vigorous. Kindly advise. Many thanks.
