I think so. What helped me figure it out was I was using a dildo to practice. It was six inches around, and very soft. I would get it slick with a combination of saliva and flavored lube, stick my tongue out, hold my breath. Once I could feel the head at the point of resistance, I'd kind of turn my head from side to side like I'd seen women do in porn. and then it would just pop in. After many repetitions of that moment of getting the head in, I got used to the unusual sensation of having something in my throat, and was less distressed that my airway was blocked off completely. As long as I kept it slippery, I could get that dildo all the way in and out. I found this translated very easily to the real thing.
