No.
You may not realize that, for most women, the clitoris shrinks and flattens right before orgasm.

OK, here is my wisdom on this subject. A friend of mine gave me 3 rules to always follow. Not to mention a lesson on a banana.
- Never EVER use teeth.
- Swallow. If it’s already in your mouth, why bother geting rid of it?
- Don’t do the same thing for too long otherwise you will both get bored.
There is some disagreement on the third one though, someone else told me that if something is working to kepp doing it and dont do something else. Well, I’ll never know who was right. I guess it varies from person to person.
Just my 3 cents. I find it easier to give blowjobs if the person is very large in the 69 position. I like to think I can do it pretty well in almost any regular position though.
HUGS!

The underside of the head of the penis is a very sensitive spot. Swirl your tongue in circles around the head and occasionally stop and flicker you tongue over the skin of the underside of the penis. Very effective! 
While doing this you can do what Diane suggested with “the spot” but I don’t use my knuckle. I just use my thumb to massage that area.
As for swallowing… it doesn’t matter. As long as you finish the job most guys don’t care either way. They prefer that you swallow but you don’t have to.
Question: just how much semen does a man expell during orgasam? I’ve heard it’s about 1/2 cup but don’t know if that’s very acurate. Seems like an awful lot to me.
Not nearly a half cup! it’s more like a tablespoon or two on average. Cecil addressed this tangentially in his article How many calories in the average male ejaculation? In that answer, he remarks that in terms of volume you’re looking at about five cubic centimeters.
It just seems like more because the guy is holding your head down.

It’s where I learned all my cunnilingus techniques, and I’ve been told my technique is impeccable.
sorry, just had to post as it’s my 69th post!
Suzeanne said it
But you forgot the part about her having big ears…
I can’t stand direct clitoral stimulation. It isn’t at all arousing, and while it isn’t painful, it’s close. I prefer stimulation to the hood. Constant, steady stimulation. Suddenly changing the rhythm, or stroking in a different direction, just breaks my concentration. I hate that ABC thing.
(Please tell me I didn’t just say that.)
And thusly, the thread was resurrected.
And there was much rejoicing, for there can never be too many oral sex discussions on the boards.
Damn. I didn’t even notice the original post date…
Remember, if y’all enjoying it, y’all doing it right.
My mouth is very small and my SO is very not small. You have to use your hands as advised, and every other advantage there is, including sound effects and visual aides. Mirrors can be your friend. Men tend to be very visual, and the sight of you doing what you’re doing could be a very enjoyable thing for him. And some aural sex, the noises you generate, can make him feel very, very yummy.
It’s (ahem) hard to keep a good thread (ahem) down.
Interestingly, my alma mater just did a story on this:
http://www.dailybruin.ucla.edu/db/archivedarticles.asp?ID=4053&date=5/4/2001
From the article:
“By the way, everyone should also learn how to put on a condom with only their mouth; it’s a neat trick that will impress many a man”
Presumably, “everyone” doesn’t include strictly heterosexual males putting ones on themselves. Then again, this might very well impress me, though I have no intention of wanting to see it done.
[sub]Oh, and I just have to add that I never read anything remotely this interesting in the school paper in my four years and one quarter of going to said college.[/sub]
Guys, what’s the best thing about getting oral sex from your SO?
Ten minutes of silence.
