Yes, I have. I've had them from masturbating and with a partner with fingers, toys and occasionally se if I'm in the right position. Um, it feels, deeper sort of than a clitoral orgasm. Where a clit orgasm is like an explosion, a gspot orgasm is like an earthquake- long, shuddering and deep. Getting close? It feels like a wave is building pressure inside me and eventually it will break loose. Sometimes it feels like I am about to pee, but I don't really have to go. All my muscles start tightening in my body, sometimes I have a hard time not rocking my hips, but I do that part with a clit orgasm too. Get her warmed up with lots of kissing and foreplay, leave the gspot for last. When you do, use your fingers, apply a good amount of pressure and most importantly watch what she does. She'll give signs as she gets closer. Part of it will be her relaxing too though. Hope I helped!
