Was this an orgasm? did i come?

well i could feel he hit the G-spot inside my v***** , and then i could feel the build up and then all of a suddenly i got this tingly sensational feeling, my whole body went numb, and the tingly feeling ran through my stomach and v***** , i felt like i was nearly passing out, then when that happened my v***** suddenly started contracting tight then releasing again ((it felt like what a guy does when he comes and you can feel it, while he is still inside you, that sort of pumping thing the p**** does )), it did this about 3 - 5 times then the whole feeling went away and i felt relaxed, so i think this is definitely an orgasm without a doubt? correct me if i'm wrong? but does that mean i come though? i often always do end up soaking wet afterwards too, like a lot...
