During orgasm, the muscles in the genital area contract and pulse, I know it’s pelvic floor muscles.. What I don’t understand is WHY they do that during orgasm.

Things are the way they are because of evolution. But that doesn’t mean everything has a “purpose.” The other answers have provided the main reasons people think it happens, to facilitate getting the sperm to the egg.
