Start slow, then increase speed and pressure up to maximum!

soft, slow, lots of tongue, cooing, no teeth

... unless a guy specifically asks for them to be involved thought sorta went w/o saying haha

just attacking  like it's a popsicle on an hot August afternoon is desirable.  

but I have a VERY sensitive tip, so I like all the significant pressure to be on the shaft - especially as I get close to cumming.
I should probable just direct ladies to ignore the tip altogether...

Heck, I dont mind even a bite here and there. Just as long as the skin does not break. However, a nice kiss to the head after some rough cock worship is always a treat.

You want to charm it and have it in your control. You take it with your hands softly yet firmly at times. It's all about the right touch at the right time . Am expert will know by paying attention to her man. The best one is one that uses variety. No two BJs are alike. Have fun with it then use it. Mmmmm use it. Giving one is like a long, sweet, wet lingering kiss.

Will you marry me?

a very amazing technique is her slow sensual tongue glide from base to tip, and when a lady presses the meat of my cock against her cheek opening her mouth eagerly drawing it inside her wet and warm mouth adding her desired amount of pressure and touch of tongue with moist suction. best enjoyed as one is sliding their tongue inside her tasty silky smooth pussy with their wet fingers exploring seeking a glowing pulsing of her pelvis into ones face

the best part is the suction.  While DT is really a turn on, along with use of hands, kissing, licking and using the tongue and mouth, often suction is lost in the effort.  A lady that can actually suction to completion is an artisan not to be missed.  Using the mouth in and out will get the job done.  Adding some significant suction to the event takes it over the top.  That said, a bad blowjob is great!  

That's my girl!  I true believer.

Slow and light or attack mode?  Licking, sucking, teeth?

Blowjobs are like pizza. No matter what, it's still a BJ.

and how sensitive the cock is. Uncut dicks are going to be more sensitive. But you can't go wrong with a soft and sensual BJ with lots of tongue action (licking the head and shaft, especially underneath the head). Lots of spit to lube it all up and make it nice and warm. I love it when you suck the head and swirl with your tongue. Then increase the intensity and suction as the guy starts to climax. A good bbbj to completion is all about rhythm and timing.

'I know it when I see it.'  I think the same is true of a great BJ, I may not know how to describe it, but I know one when I've gotten one!  I agree with a lot of what's already been said, the one thing I want to strongly concur with is the view that the ladies who truly love doing it are also the best at doing it.  But I also agree that the worst one I ever got was still pretty wonderful!

I have extra sensitive balls that just crave being kissed, licked, sucked, and otherwise fondled. The best I ever had was by an old girlfriend. She would suckle my balls one at a time, roll them around in her mouth with her tongue, gently sucking and teasing me. She would stay parked between my legs for hours -- or as long as I could stand it. Oh my goodness!  

Anyone that had seen me and likes what I do hears the story... For an entire summer around 22, I had a tutor. A guy I knew and liked offered to teach me exactly how to give a great BJ. The teachings were intense and often went on for over an hour. On my knees in front of a full length mirror. Not only did I have to make sure I was sucking right, I learned to use my hands, watch my breathing, spit control, rhythm, and most importantly his expressions for when I was on the right track or if I needed to do something different. Best lesson of my life. Always be eager to please and responsive to your partner and the rest will eventually fall into place.
