This subject has been thoroughly reported in previous threads, what the heck, here's mine again.
Because of the big hurrah a friend made over the amount of my explosions, we got a jigger measuring glass to actually 'catch' my load. One and 1/2 ounces equals three tablespoons, therefore, Geo might well have a climax with that much. Mine was over two tablespoons, just a bit below what would measure 1 and 1/4 fluid ounces. The amount bears no relation to the dude's size of any of his physical properties. Its dependance does require keeping super hydrated, though. One benefit of large amounts each climax is the number of shoots and the length of the streams. Lots of folks are impressed by these showoffs.
