Interesting! I love g spot more. For me it is an incredibly intense, divine feeling that makes my eyes roll back - and They last as long as he is touching that area, so they get so intense sometimes, I have to laughingly ask him to stop! For me, I mean multiple in that I will have that feeling any time he is touching that spot in the right way. So we often move out and back into that position (best on my back, legs up in a v in front of him, him kneeling between my legs, his torso vertical with vigorous movement... even more intense if I do a little tummy crunch or have a little in my bladder)... I don't have a sense of build up, then release, then oversensitivity with g spot that limits the repeat. Other than feeling relaxed and receptive, I don't need any foreplay at all. I also don't get a fall in my sexual desire after.... so we just stop when I feel totally satiated (and a bit dizzy!)
Clitoral is an amazing sensation, but has some disadvantages - I need build up and definitely sometimes just can't, and I lose desire as soon as I have come in this way- feel tired and just want to lie there, so if it happens not at the end, it's a bit of a bummer. There's also a bit more performance anxiety ('trying to come/ will I/ won't I etc...). And I have never had that full radiation through my body - it feels awesome but sticks around my pelvis.
I've never experienced both at once, as for me they need totally different positions, moods and vigor....
There was a third kind of orgasm I found when I read a book (was it called 'massive extended orgasm?' Something like that.). It was incredible - maybe more on the tantric side, with a lot more 'mindset/setting' stuff and massage of one specific section of the clitoris... it was probably the most intense physical experience I have ever had, and did radiate through my body- there was no 'arrival point' just ever growing sensation for as long as you want to feel it. (The book described the 'arrival - oversensitivity kind of orgasm as the 'sneeze style' and interestingly suggested that it was a much more masculine form of orgasm and women had somewhat been led to believe that was all their bodies could do, because it fitted best the male paradigm of sexual pleasure) I got into the habit of giving myself this kind of orgasm for a short time on my own, while single, and walked around in a totally blissful state! But it takes patience and I have fallen out of the habit and have never tried it with my partner.
Anyway OP, I realize I have strayed a little from your original question , but I hope that hearing women's accounts can help take away some of the taboo and open up possibilities? If you are able to have orgasms in private, and have a partner willing to learn then I am sure you can achieve orgasms with him- it may be a case of casting off some of the mental beliefs or anxieties you have rather than learning anything physical. It can be a wonderful exploration!
