Ask your guy to empty his bladder. This is to promote his comfort zone. Drape your client for privacy. As you begin your physical assessment be very sharp with your observations and try to compare what you see on his side of the body with the other side and compare with normal.
While you are doing your physical assessment skills, make use of teaching opportunities on dental care, eye exams, and self exam of breasts if the client is a she and for the testicles if your client is a he. Use appropriate piece of equipment for the entire physical assessment, then return your tools on the equipment tray.
