These provide a good fit for the Male anatomy due to the stretch of the fabric.  However, that stretch also makes the waist band a bit big.  I am always a mens medium which is a womens large, so that is what I ordered.  These do fit, but tend to fall down a bit.  The fabric is more cotton like and I tend to prefer the polyester/nylon fabrics for the smoothness.  These work, but the fabric and the super stretchy waist took 2 stars off for me.
