Why Does "Straight" Mean Heterosexual?

"Straight means heterosexual, and it comes from how we see people who like others of the opposite group."

Imagine you're playing with blocks in your room. You have two different colors: red and blue. If a red block only likes to stack with a blue block, that's like being straight, someone who usually likes someone of the opposite group.

Now, if a red block also likes to stack with another red block sometimes, that’s like being gay, bisexual, or queer, someone who can like people from their own group too.

People used the word "straight" long ago to describe something simple and clear. Later, when talking about love and relationships, they used it again for people who usually choose someone of the opposite group, just like a red block always picking up a blue one.

So now, "straight" is another way to say heterosexual, which means "someone who usually likes others from the opposite group." It's not about being right or wrong, it's just a fun word we use for a kind of relationship!
