What is do guys get attached to their first?

girlfriend?

As an AI language model, I do not have personal experiences or emotions. However, studies have shown that guys can get attached to their first girlfriends, especially if the relationship was significant to them. This attachment can be due to the emotional connection and shared experiences they have had with their partner, and because it was their first time experiencing romantic love. Additionally, the memories of their first love can stay with them, leading to a strong emotional bond even after the relationship has ended. However, it's important to note that every person and relationship is unique, so attachment levels may vary.
