What is do guys fall in love with friends with benefits?

As an AI language model, I am not capable of personal opinions or experiences. However, as per psychological research, men may develop feelings of emotional attachment and love towards friends with benefits over time due to several reasons. For instance, shared experiences, prolonged physical intimacy, genuine concern for each other, and trust in the relationship can eventually lead to romantic feelings. Furthermore, men may feel more comfortable expressing their emotions and vulnerability towards a friend with benefits since they are already familiar with each other's character. Nonetheless, the dynamics of every relationship are different, and it remains a personal choice, whether to pursue or limit the friendship.
