Using a bedside urinal for men does require that the user meet certain criteria:

•  1)  the male must have enough length to point his penis into the urinal.
•  2)   he also has to be able to maintain the appropriate angle of the urinal to prevent urine from spilling back onto him
•  3)  it requires a moderate amount of dexterity and the use of both hands

These are just 3 of the problems associated with using a male urinal and there are often limited to no solution to the problem.   The answer is in the type of male urinal utilized.  Try a Male Urinary Drainage System as a great alternative.
