How do guys like their blow jobs to be done?

do like porn star do, guys watched so many porn movies they become aroused by what they used to see, sometimes I think visual blow job is better than paying all attention on the physical side

up and down on shaft.slowly.and the quickly as you see the guy likes it more and more.

I'll have mine well done please.

Quickly,and up and down the shaft of the cock.

There are many crazy techiniques which most guys find very nice, however once again, it's personal experience.

Try deepthroating, as far as you can, but don't push your luck.
Try moaning. Try swallowing and continuing to clean his member once he is done.
Try it for foreplay. Try sucking the balls if they are shaved enough. Try tonguing the knob.
Try going fast at different depths.

I'm sure he will open up as to what he is enjoying. The number one key I can give you, is enjoy what you are doing as much as you can.

Yes! most definitely.As long as she's sucking my dick I'm Happy !

Actually it varies heaps, the only answer I have is TALK (well not with your mouth full, that's rude)
but its cool to ask, we don't actually ever judge a girl by her oral skills (first time round lol)
As long as he thinks you are digging the fact that you are sucking his dick he will be very happy, that's half the fun is exploring different ways and assessing the result, trust me you will know when you get it right (teeth are not usually the preference I must say) A nice deep long moan (grrr MMMMM) makes a very nice vibration when you are going deep!

ohhh.nice question. but I think you have answered you own question. on the knob is just awesome as with a bit of teeth . its that variety that keeps it excitement there. if you keep add in all that, you won't have a problem. enjoy

No teeth that hurts like hell never ever use teeth, I had a girl who used teeth one time and I told her no teeth no biting good god that hurt., it made me want to slap her in the face, I didn't of course but oh man it made me want to. Just go slow and easy.
