Why so eager to trade?

There are many possible reasons to trade. You might trade to damage the opponent's pawn structure. You might trade in order to make the opponent lose castling rights. You might trade because you feel like you are stronger in endgames. You might trade a good piece for a bad piece. You might trade to gain a lead in development if the opponent has to capture back with a pawn, losing a tempo. You might trade in order to win a pawn (removing a defender). You might trade in order to gain space in a cramped position. You might trade the Queens, if you have lost castling rights or your King safety is otherwise compromised or you are under attack...

Many reasons to trade, none of them lame really.

Some people trade pieces because it simplifies the position and allows them to process the opportunities and threats more efficiently . Players trade queens because it removes a powerful threat from the opponent and the king has to capture it thereby preventing it from castling and there is a chance that the opponent can use it efficiently and better than you to wreak havoc and checkmate you . So they capture it in exchange for their queen when they get a chance . However all players do not do this , they don't leave their queen vulnerable to being captured by the other queen but open a new path for it and move it before opening the position.

There is nothing lame about trading queens. Very lively games can result after trading queens.

This is a common beginner mistake in many situations because they believe trading simplifies the position, but not always is this true. I made an older video on why this is a bad idea:

Sometimes they give you no choice.

Sounds like the OP is scared of playing without a queen being present in the game.
