[QUOTE=sdking;153349]My gf can barely fit half of my penis into her mouth and i really don't get any pleasure from it. If feels good, but i want more (I'm selfish, I know). Is there any way she could learn to relax her throat so i can fit more in?[/QUOTE]
It's possible, but I don't think more than 1 in 10 women can do it. Maybe more, but it's definitely a minority.

I'd say, by rough estimate, that about half (or a little more) of a normal-sized penis will fit into a normal-sized mouth. To get more in there requires the head actually to go into the throat (i.e. her to "deep throat" you), which I don't think is easy for most women.

Frankly, if you "don't get any pleasure" from ordinary oral sex, I doubt you'll get much more from deep throat.

Most women will use there hand as an extension of their mouth.. and just use their lips and tongue to focus on the head.

She should get better with practice. Very few woman can get much in the mouth at first. Just relax and enjoy what she can do and it should get better. My wife has gotton better at taking more of it in her mouth but that is after many years of practice. I usually ejaculate with her on the head and she or I am using out hands down lower. It is only recently that she has been willing to have me cum in her mouth and swallow. So each proceeds at their own pace. Just be happy she is even willing to give you oral since there are a lot of women that won't do it.

If she's getting half of it in her mouth (assuming by "half," you don't mean the left half or the right half), then size isn't an issue.

Sensual pleasure and/or physical delights are more a matter of technique than placement. In other words, I do not believe that learning how to be a "deep throat" artist is going to do much for your psychological pleasure, although it might be a big ego trip for some macho types.

I believe it better if the two of you spend some time learning how to pleasure each other always in all ways. Learn the art of pleasuring each other's body and skin with kisses and caresses and how best to stroke a penis and finger her pieces-parts. The same recommendation holds for oral sex and combining oral stimulation with a hand job. Learn where his hot spots are located around the Corona Rim (do not overlook or ignore the Frenulum!!!), and then how best to work your magic. If you are not feeling anything, then I offer the thought that she has yet to learn what type of stimulation by way of lips, tongue and fingers will light your "fire".

Read the tutorials available on this site and either buy the "Joy of Sex" book and/or one or more other sex manuals, plus, have a look around the internet. GOOGLE and Ask.com are good providers of information.

[QUOTE=sdking;153387]I guess the best tool in sex is communication[/QUOTE]

You're learning.

The next best "tool", the one between your legs, is important to her because a woman considers the penis as a combination throttle and brake over which she has complete control over her man's arder and progress toward nirvana. For guys, size really does not matter. As long as she can grasp it, it is big enough. What should matter most to men is that we become knowledgeable, skilled, caring, compassionate, lovers, and know how to use what Mother Nature endowed us with.

Plus I thought most of the "feeling" was the head and around it... not down low the bottom of the shaft?

Its just one of those Catch 22s. Some men wish they had a HUGE penis but forget most women cant do much oral on that. Where as women usually will enjoy giving oral to a man who is average or smaller than average.

> Plus I thought most of the "feeling" was the head and around it... not down low the bottom of the shaft?

As an aside to all this and to shed some additional light on what you thought is to say that you are correct; however feelings do go much deeper. Let me explain.

The Glans is extremely sensitive, even more so with men who still have a foreskin. For those of us who do not you can do much with it to drive us wild. For example, you can slightly cup your well lubricated hand and rub around the top, sides, and tip, using a hand action like polishing a doorknob. This will cause a man great pleasure and more often than not he will become quite animated and vocal. The same holds true for letting the head slip between your lips and letting your tongue do its thing. Add and involve his hotspots of which there will be one or more distributed around the Corona Rim (in addition to the Frenulum) using your fingers and he'll be putty in your hands. This is the dynamic duo I sometimes describe.

The shaft has surface nerves that come alive when well lubricated fingers lightly graze over it, especially so when he is very aroused. When using a dry hand, squeezing the shaft tightly, moving the skin back and forth within your grasp involves more deep-seated nerves. You will discover, perhaps with his help, that there are specific areas of the shaft that when squeezed and rubbed also react as hotspots.

The external appendage of the penis is akin to the trunk of a tree, there is much more below the surface. The root structure in the abdominal cavity also has nerves that can be involved, particularly if you rotate the penis in a circular motion about the base. Doing so when he is near the trigger point of an orgasm will surely cause it to happen, also.

It is because of all these hotspots and their individualities and how each guy has come to involve them over time with a specific set of motions, rhythms, and pressures that I urge women to learn how he masturbates and then to let him guide their hand several times until learning how to mimic the movements that are unique and specific to each.

As an aside in a different direction: for the woman to get the whole thing in her mouth, she has to do a "real" deep throat (unless, I guess, the guy is really quite small). To do that, the head actually enters her throat, and the narrow part of the throat stimulates the head in a different and interesting way.

But:
- Not very many women can (or maybe want to) do that. One in ten is a rough guess.
- It's just one item in the menu of dozens of interesting oral sex tricks.
- Oral sex tricks are just one aspect of the whole sex thing.
- Sex is just one aspect of the whole relationship thing.
So it shouldn't be blown out of proportion.

So far as I can tell, I don't see penis size as being much of an issue in oral sex, unless the guy is so wide that she can't get her mouth around it at all. In which case, that's just one of the problems that guy is going to have (passing out whenever he gets an erection being another).
