all masterbation for me, im sure with an actual female in the room it will be an incredible mess,
but most of the time i just ejackulate in to my mouth, and obviously this reduces the excitement etc etc, and thus i dont blast it or anything. its just for easy clean up reasons, good self containment.
but ive made huge messes, back when i use to shoot it in to the toilet bowl, i use to crouch in front of the bowl and shoot it in to the back wall of the bowl with some force.
for fun, ive stood in the laundry behind a line and shot it to see how far away it lands, based on the toilet bowls i thought itd go further, but instead it only traveled like 3-5 feet. but i suspect it wasnt a huge ejackulation because its kind of a bizzare situation.
anyways my biggest ever ejackulation, i was sitting on the edge of my bed, the mirrior is about 1m away, and i just completly blasted it, there was heaps all over the mirror, and there was also puddles and splaches all over the floor i think i remember counting an indivudal amount of 80+ groupings of cum, some small some big obviously but 80+ or 76 or 82 or somthing actual drops / splashes of cum, half on the floor, half on the mirror, the ones on the mirror were blasted with force, the ones on the floor was like "sporadic side damage", cos the blast isnt concentrated in one place its like an uncontrollable spewwing in all directions of white shit.
anyways i would think of myself as a big mess shooter, but i think i empty the old balls too often! and also i dont go for the big mess shot except when i have the house to myself and im up for that kind of "Game sports-ness" of that act.
since i use my muscle in my cock to stop ejackulation frequently, i feel their is sperm inside my cock and shit, and or somthing, anyays that fucks with the ejackulation too. the optimum conditions for a huge ejackulation is a marthon masterbation without any "woops" moments wherre by u fight like hell not to ejackulate. just one moment and that is before the big money shot. and thats after hours of stimulation and super hard boner and also like 24 hours since the last ejaculation
