For me as well - the deeper the stimulation goes the more intense the resulting orgasm (but also the longer initial build-up to the orgasm itself). Trying to put things into words - which will certainly fail - but an attempt.
Clitoral orgasm - sharp, throbbing, felt mostly superficially and concentrated to the clit and a bit deeper down; passes fast with almost no residual effects, hard to come a second time as the clit becomes extremely sensitive to touch and withdraws
G-spot orgasm - warm, almost itchy, pulsating build-up that releases into warm waves and contractions of the entire vaginal area; stays for quite a bit longer than a clitoral orgasm and is relatively easy to get more orgasms with continued stimulation
AFE-spot orgasm - almost electric in build-up with dildo/cock hitting the back wall of the vagina and moving around, intense release with contractions of the entire lower stomach (visible to partner), similar to period cramps but replace the pain with intense pleasure; stays for as long as stimulation is kept up and continues rolling throughout the body in new orgasms that ebb and flow into one another; body exhausted and drenched in sweat afterwards, sensitivity stays for a long time, enough that even just light touching up to 24 hours later recall some of the sensation.
And yes - I very much prefer the AFE-spot to anything else - I'm also lucky that I have a man in my life that give them to me regularly enough that I spend much of my time with him weak in the knees, hoarse and smiling like mad. :biggrin1:
