The working theory is that replicators double as toilets.
It's how they collect/recycle biomatter to make food.
So don't be so quick to disassociate replicators with orgasms.
Pretend that you're a man.
You set the rplicator to wall in the replcator pad alcove with a wad of soft luke warm moist Russsian fudge.
To quote a very early episode of Friends...
"I honestly don't know if I'm hungry or horny!?"
"Then stay out of my ffridge!"
