How do you know if a man has an unhealthy penis? -

(serious question please

kind of a broad question...

But maybe it isnt functioning normaly?
some sort of pain or irritation?
Bumps or discolorement on the penis?

Lots of things

If the foreskin will not retract freely, easily and completely then he cannot be washing himself properly.

Any signs of significant amounts of smegma under the foreskin again shows a lack of penile hygiene.

An inflammed glans or foreskin is a sign of an infection, as is any bad smell or discharge from the penis.

If its green and furry and the balls are orange and sticky, with yellow patches.

any discharge or change in bladder habits eg how many time you go to toilet

I think you need to fine tune this question!
