Squirting orgasms are way easier for me that clitoral ones. What are you missing? Well, just a different experience. Just like anything, it is just a different experience and if it is not something you facy, or are even turned off by it, then I would say you are not really missing anything at all, because it just isn't for you.
The way I would describe it, is that g-spot orgasms are just as intense as clitoral orgasms, however, they are completely different in sensations. A clitoral orgasm builds slowly, until you reach a peak and then you fall over that peak and it is like an explosion for 10/20 seconds of orgasmic contractions and feelings. A g-spot orgasm (for me) builds quickly and the intensity peaks and peaks and peaks and the squirting is the release, the satisfaction, but there is no falling over a cliff and having numerous muscle contractions. It is simply peak peak peak...release and feel satisfied.
My g-spot orgasms satisfy me in similar ways to clit orgasms. I feel relaxed and content afterwards, and often they can satisfy me to the point that I no longer want to orgasm clitorally. The g-spot ones have sated my arousal in the same way a clit orgasm would. The other way round is different though. If I start with a clit orgasm, I often want to go on and have g-spot orgasms, as the area is even more sensitive and swollen and they feel even better.
There has been a bit of debate as to if a woman if just peeing or if the fluid is something else. I don't think I found a definitive answer, but I have found information about tests having been done on the fluid, compared to the womans urine and the squirt fluid shows much higher levels of something or other and seems to be different to urine. Nothing definitive though. I can tell you, as a woman who has been enjoying squirtinf for many years now, that I have actually sometimes peed instead of squirted, while being stimulated intensely, but therein lies a little fact....I can actually tell the difference. While it does come from the same piping (The urethra) there is something slightly different about the feeling of squirting, and the feeling of peeing. It is noticeable, but a subtle difference. It even went as far as my guy noticing the difference. On one of those nights when I was sure I actually peed a little as well as squirting, he said he noticed I had peed that time but didnt want to say. I think it was the smell (TMI but thats the truth. it smells different)
All I know is that it feels amazing and like another person said, I could not choose between only having clit orgasms, or only having g-spot ones forever more. It feels good so I don't care what the fluid is. The fluid is the outcome of a very good time. Thankfully my partner helped me accept that even more, by not being at all deterred by the fact that I once peed on him. lol
