See a urologist. You have a urinary tract infection, or sexually transmitted disease. Both require treatment by a doctor or you could suffer serious long-term effects.
No you should not attempt this as you can bleed to death.
Your penis should not bleed at any age, I'd advise you to see a doctor, it may be nothing serious but it is better to find out for certain.
Remove fitting at junction block (usually at center of rear axle) and disconnect at the wheel cylinder Replace line and bleed air from that wheel. Should only have to bleed that line
Not normally. See your urologist.
No it isn't. You are definitely doing something wrong.
You should never had to "bleed" a fuel filter. Any air in the fuel line should come out as the fuel pump pushes fuel through the line and filter to the carburetor. There will always be some air or open space in the filter.
It shouldn't. Take the dog to the vet.
Remove cap from PS pump and turn wheels "lock-to-lock" several times. This procedure should bleed air from PS lines.
The urethra is very delicate, and any rough handling, including catheter removal, will cause it to bleed.
Bleed it out
You should not have to bleed the fuel line if the system is all ok just cycle the fuel pump a couple of times by turning the key a couple of times and the air should use the return line back to the tank
There could be many reasons for this. It is impossible to answer the question without more information. You should see a doctor for proper medical treatment.
