I’m talking about humans specifically here. During school I was always shown animations that showed many sperm swimming to an egg, and then when the first sperm started entering the egg (don’t even know how they do that, do they eat through?), the other sperm just stopped trying and gave up. How do the other sperm know? Are they sentient? What’s stopping loads of sperm going into the same egg? What would happen if 100 sperm went into the egg at once?

They don’t. Sperm swim until they run out of energy and die. Once the egg is fertilized, it rapidly forms a layer that blocks addition sperm from entering the egg, perhaps that’s what you are thinking about?
