The terms “throuple” and “triad” are often used interchangeably to describe a relationship between three people. However, there is a difference between the two terms. A throuple is a three-way romantic relationship between three people of any gender combination. A triad, on the other hand, is a three-way romantic relationship between three people of the same gender.
A throuple can be formed in a number of ways. The most common way is for two people who are in a relationship to add a third person to their relationship. This can be done with the consent of both parties or without the consent of one party (known as stealthing). Threesomes can also form from polyamorous relationships or swinging lifestyle agreements.
A triad, on the other hand, is typically formed when two people who are in a relationship decide to add a third person to their relationship who is also attracted to both members of the couple. Triads can also form from polyamorous relationships or swinging lifestyle agreements. Unlike throuples, triads are usually more stable and longer lasting because all members of the relationship are attracted to each other and have an equal say in decision making.
