I don't, but I want to get one for my husband for his birthday. If I get the dock, can 2 people play the same game of it's on a TV or do I need 2 decks?
No, you don't need two decks. You need:
Steam Deck
USB-C Dock with power delivery (for example, the official dock)
1 to 4 game controller (most bluetooth controllers will work fine)
However, there are not very many "Couch Multiplayer" games on steam. Most multiplayer games are online.
adding to @cron@feddit.de there is whole genre of indie games targeted for couch coop for couples. there aren't hundreds of excellent games but definitely a dozen. It would definitely deserve it's own post but on top of my head you have: portal 2, Lovers in dangerous space time, it takes two, a way out,

I think there are a ton (of great) local co-op games on steam.

Children Of Morta works for couples as well.
