Oh Nikipedia! What trouble you are asking for! ;-)
A person who gives a good blow job, above all else, knows how to play their partner. Like playing any instrument, practice, practice, practice. You may never be perfect, but you will become awfully good.
When you “play” your partner, you are not just finding the good spots, but you are paying attention to every little signal. You know how teasing works. You play around the tip of the penis with your tongue, but you don’t engulf it—not yet. You want to make your partner beg for it. You know how to play between the standard and the unexpected. Sucking his cock—sure, but also licking that sensitive part behind or underneath his balls. Teasing with your tongue. Sucking in a ball, squeezing a little, making him wonder—dancing on the line between pain and pleasure.
Eyes are so important. Looking up into his eyes, catching his look, smiling as you engulf his cock, showing your pleasure. There is nothing you would rather be doing. You would beg to be allowed to do this.
Blowjobs are a curious mix between submission and power. The man loves to lay back, just being allowed to be pleasured. The idea that his privates are the focus of someone else’s pure attention is intoxicating. For the giving person, there is a sense of power—of being able to make this guy whimper and groan.
The psychology of it is more important that the physics of it. The emotions must be played. The physics are important, but they can be learned by a willing partner. In fact, there is an extra excitement in telling your partner exactly what you want him or her to do.
It probably does help to know a bit of anatomy. The tip of the penis is for teasing. The base of the cock is for pumping. The balls are for squeezing or sucking. Tongue, hands, fingers—light touch to tease, stronger touch to finish off. Imagination, too. You will learn to feel every little movement and sigh, how to make him beg for more; how to make him moan.
For many men, the blow job is the best kind of sex, ever. Although, no one wants to have to choose. We want it all. We want the given; we want the forbidden. We want both the tease and the sleaze. We want you to take us deep. We want you to wake us from our sleep.
Now go forth and suck!
