Ok - so this is very similar to your other question to which I answered:
My wife can orgasm from just using the Pure Wand on her g-spot (i have done it for her as well). It takes a lot of time and patience - so she doesn't prefer it.
We've become very adept at blended or combined orgasms. They are way more intense and satisfying that clitoral-only orgasms.
She had two huge ones tonight - she couldn't move or talk for about 5 minutes. I love when that happens! She calls it my job security!
Adding to this I'd like to say that you are very young - indeed in many ways not even fully mature. Similarly your partners are likely relatively inexperienced - be patient - don't give up.
My wife insists that I know her body better than she does - and indeed it's very true. I can reach her g-spot and deeper a-spot in a way that she never could with or without toys.
Until you find the right partner - don't put a lot of pressure on yourself - its a lifelong journey of discovery. If you had it all today what would there be to look forward to?
We continue to love and explore - enjoy the journey!
