No, friends with benefits (FWB) relationships typically do not involve money. Friends with benefits is a term used to describe a casual relationship between two individuals who are friends and also engage in sexual activity together without the commitment of a romantic relationship. The emphasis is on the "friends" part of the arrangement, meaning that the primary connection is based on a friendship rather than financial transactions.
In a friends with benefits relationship, the individuals involved usually enjoy each other's company and have a physical attraction, but they do not seek or expect a traditional romantic relationship or the emotional commitment that comes with it. The arrangement is often seen as a way to explore sexual intimacy with someone you trust and have a connection with, without the expectations and responsibilities that come with a more serious romantic partnership.
Money should not be a factor in a friends with benefits relationship, as it is not the defining aspect of the arrangement. The focus is on the mutual understanding of the casual nature of the relationship, respect for each other's boundaries, and clear communication about intentions and expectations. If money becomes involved, it may indicate a different type of relationship dynamic, such as a transactional or sugar dating arrangement, which is not synonymous with friends with benefits.
