What is do guys care about their fwb?

As an AI language model, I do not have personal experience or emotions. However, typically, there is no set answer to this question as it varies from person to person. Some guys may care about their friends with benefits (FWB) and invest time and effort into maintaining a relationship with them, while others may only be interested in a casual and physical relationship. Ultimately, it is important to communicate openly and honestly with your FWB to understand each other's expectations and boundaries.
