Oral Sex Technique - I would always comment to myself when someone went all the way down on me that if I could get my throat that open I would be a much better singer. And you know what? I was right! Lowering/stretching down the back of the tongue creates a cavity that allows for deeper insertion. The better I get at it, and the more I practice
, the easier it is to maintain that open position when I sing. Combine that with a relaxed jaw and proper breath support, I have better pitch, vocal agility, and the warmest tone I've ever had. I have to admit however, unlike David mentioned earlier, I have not learned how to breathe through my nose when my friend of the moment is all the way down there.
