that's porn, desu
you've come to associate the money shot from porn with fulfillment because porn 99.9% of the time never shows simple internal ejaculation (creampies are always spilled out, etc) so the positive association of orgasm is the visual of cum
it's a dopamine feedback loop,
positive association -> orgasm -> dopamine feedback loop -> seeking behavior
start jerking it to softcore or nudes and don't watch yourself cum, and cleanup once you're in the refractory period and the cum is cold and gross, and you'll stop associating cum itself with anything positive and it'll go away in a few weeks
