There may be bacteria in or around the urethra but they normally cannot enter the bladder. A catheter can pick up bacteria from the urethra and allow them into the bladder, causing an infection to start
bacteria enter your urethra.
Same reason as women - bacteria in the urethra.
No.Normally, urine is sterile. It is usually free of bacteria, viruses, and fungi but does contain fluids, salts, and waste products. An infection occurs when tiny organisms, usually bacteria from the digestive tract, cling to the opening of the urethra and begin to multiply. The urethra is the tube that carries urine from the bladder to outside the body. Most infections arise from one type of bacteria, Escherichia coli (E. coli), which normally lives in the colon. In many cases, bacteria first travel to the urethra. When bacteria multiply, an infection can occur. An infection limited to the urethra is called urethritis. If bacteria move to the bladder and multiply, a bladder infection, called cystitis, results. If the infection is not treated promptly, bacteria may then travel further up the ureters to multiply and infect the kidneys. A kidney infection is called pyelonephritis. Pubic hair has nothing to do with UTI.
An urinary tract infection happens when bacteria travels from the urethra to the bladder. Incubation times varies from a few days to a few weeks depending on the type of bacteria that caused the infection.
Bacteria naturally lives around the opening of the urethra. Friction can cause the bacteria to get brushed into the urethra and the bacteria flourish in the warm, damp, dark space. This causes a UTI.

infections
Bacteria can enter the bladder and ureters through the urethra, which is the tube that carries urine from the bladder out of the body. This can happen through activities like sexual intercourse or improper hygiene practices that allow bacteria to travel up the urethra and infect the urinary tract.
The histology (tissue structure) of the urethra makes it an easier target for infection than the squamous epithelium of the external penis. For this reason, contact with an STD is likely to infect the urethra.
Yes - obviously bacteria and dirt can get up there, that's how urinary tract infections come about, you can force things up the urethra but this is not recommended as it can be painful and cause damage.
Yes. The urethra is shorter. Thus, bacteria can reach the bladder more easily. Also, the proximity of the female urethra to the anus is closer. Therefore, bacterial "seeding" of the urethra can also occur more easily.
