"Straight" typically refers to a sexual orientation where a person is attracted to individuals of the opposite gender. For example, a straight man is attracted to women, while a straight woman is attracted to men. This orientation is one of the most common in many cultures and is often considered the societal norm.
In addition to its sexual connotation, "straight" can also describe something that is not curved or bent. For instance, a straight line in geometry is the shortest distance between two points. This concept is used in various fields, including art, design, and architecture, where clean, straight lines can create a sense of order and simplicity.
