Aight, I looked it up for you. They don’t.

The females have two (more?) holes used for mating. The male grabs a silk sack full of spider sperm and with its “hands” puts it inside the holes. There the females have two (more?) spermathecae where they store the sperm. Sperms will gradually meet unfertilized eggs at a second location, and the fertilized eggs will exit from a separate hole.

Sounds kinda similar to octopi if you ask me. Anyway, I wouldn’t call any of this a pusspuss.

Apparently in some species the female eats the male after mating. Also in one species the male ties up the female before mating (kinky), it still gets eaten afterwards.

Remember that before looking up silksong smut

never have I ever wanted to know about spidussy.
