Not really. I consider myself average when it comes to giving bj's. I mean I am okay but I am not amazing at it or anything.
you must pull the balls back a bit, spare the tongue action(its not an icecream), make sure teeth dont touch the dick, and help little bit with one hand.
go soft, too hard sucking is no good(youre not some alcoholic and the dick isnt a bottle of booze).
and when the cumshot happens,open mouth wide, swallow initial load,then get off the dick immediately, or youre ruining the orgasm,wait a bit, and then can lick the rest of semen or use towel
thank me later
