Anyone here tried....

To master/do actual deep throating? Not just like shoving his dick to the back of your throat i mean past that flappy part and into your actual throat? I've been practicing and been getting better but does anyone have some tips on how to really master it? I'm still not good at it whatsoever i can only take maybe 2 or 3 thrusts at a time, is there a way to kind of really stop the gagging reflex you get? Because that's really the biggest thing in the way, that choking gag reflex thing lol also how do you maximise the whole breathing efficiency thing? I'm really keen to start doing things like the washing machine and wood pecker but I'm so noob lol really just many many tips advice please. My man is a nice 7inch if that makes any difference
