I such cock better than most women who have sucked my cock. The secret to sucking cock properly is to suck a cock just like you would like YOUR cock to be sucked. Many women suck like they are trying to run a two minute mile ....just get it over with. A man can detect when they have found a guy's "sweet spot", where and when to put the pressure, can tell when to slow down, when to speed up, Some men want all the attention on the head, some only on the shaft, hands/no hands, etc. You got to pay attention to what you are doing. Every man remembers the best and the worst blow job and hand job he ever got and and maybe some of them where by a woman. And maybe some of them where by a women because he had no options. There are three things many women don't have a sense of timing for: (1) a good blow job (2) a good hand job (3) driving stick shift. Telling a women she sucks at sucking dick is like a woman telling a man he sucks at fucking. You gota be careful how you put it. But, some are trainable. That said, I have a married buddy that can't suck cock worth a damn, he needs more practice.
