This Is The Difference Between Casual Hookups & Casual Relationships, According To Experts. A causal relationship is a physical and emotional relationship without the commitment, labels, or demands of a committed relationship. A casual hookup is a sexual relationship that only exists for fulfilling sexual needs.

What is the difference between casual and relationship?

The primary difference between these two types of relationships is that “casual daters” can have sex with multiple people without “cheating” on anyone. In other words, you are not required to be “faithful” to one person. In a committed relationship, you both agree to restrict your sexual relations with other people.
