I would recommend first getting a toy designed for G-spot stimulation. The vagina has the majority of its nerves within the first 2-3 inches inside. The G-spot is about 2-3 inches (varies per woman) on the inside, if you curve your finger towards your belly, you should find a small patch of spongey material. It will feel a little differen than the rest of your vaginal walls, in that it won't be a soft smooth touch, but rather a rigid area. One of the way I started having G-spot orgasms was to first go to the bathroom before playing (always should anyway, it helps prevent infection) The reason I say this is often times, right before you cum from a G-spot orgasm, it feels like you have to pee. And in order to tell yourself "I KNOW I don't have to pee, because I just did.. this has to be my g-spot building!" then it's easier to go potty first. Anyway, after enough stimulation, it will feel like your bladder is full and you have to pee. Don't stop stimulation or you're likely to miss that orgasm. Once pressure keeps building, you'll orgasm from it. It feels amazing, and honestly I've only recently gotten extremely good at it. But I prefer rabbit vibrators that have a metal bead rotation device towards the bottom, because if it will stimulate the first 2-3 inches, if I angle it to where the beads are rotating against the wall closest to my stomach, I know I'm hitting the g-spot. And everytime, it feels like I gotta pee!
