What's the biggest mistake girls make when giving head?

[charlet]

Be specific!

[centerline]

not knowing how to make it feel good to us...
each girl is different and has a different style, so its difficult to say what her mistakes will be... the very worst blowjob I have ever had the opportunity to be troubled with was from a girl who sucked my dick like a fish does to the side of its fishbowl... basically just kissed her way around it without any licking or sucking it...
the question may solicit more informative if it were asked "what is the best technique for giving a blowjob to get him to cum the quickest?"...

Using their teeth, sucking to hard on the balls, I prefer if she cups and plays with my balls while sucking on my dick. Not concentrating on the most sensitive areas which is the head and the back side of the head including about the first three or so inches down the back side of the shaft below the head. Does that help?

[theharshtruth]

not letting me put it in her mouth far enough with each thrust

[Tobi_Lerone]

Too much teeth, forgetting the balls or I had a girl that really sucked hard. It hurted. I usually prefer a bit harder but that was like I had a vacuum cleaner on my dick. Not so nice

[Dargil]

Getting tired and either slowing down or pausing.

Too slow and tender. Don't use both hands. You have to get naked, or at least topless.
You ever find the Stormy Daniels vids? Man can that woman suck a dick!

[Wise4myage]

Getting to carried away and biting my dick.

[SirrVeta]

They spit it out, when they should actually swallow

[Nathan65]

Using teeth, Not sucking balls

[COMMODOREII]

Too much teeth!! Lol

[GreenGold1992]

I'm still a virgin, but I can't imagine there being any mistakes in that field.

[TotallyAlmost]

Ignoring the balls and not using her hands.
