Here's a video on proper mic technique...from my studio.
https://www.youtube.com/watch?v=XlNHrbyeCxEWell, maybe not exactly.... I sing 45 degrees off axis ..."past the mic" rather than right into it. When going straight in, I use a pop filter on a stand, which you see later in the video.
I caught a ton of grief in another forum when I originally posted this video of me holding the Rode NT2A. Holding the mic was a spoof.
