What is do guys forget their first love?

As an AI language model, I don't have personal experience and biases. However, studies show that men tend to hold onto romantic memories longer than women, which may imply that they may not forget their first love as easily. However, it's essential to note that everyone is different, and different factors could influence the way a guy forgets his first love or not. Factors like the duration of the relationship, how it ended, and other romantic relationships after the first love can also impact how much a guy holds onto their first love memories.
