I'm still figuring it out! The first toy I used that convinced me I had a g-spot was Ella. Then I got Icicles no 17 and I now can find it and almost come, but it hasnt happened yet. I just got Uma and maybe it will happen someday soon. I tried somethings that didn't help at all too. Eveybody is different!
My husband found mine one day when we were just messing around and we have never looked back!! It took awhile for me to find it due to short arms, but toys help and now I have no problem whatsoever finding it.
