What is do guys get attached after sex?

As an AI language model, I do not have personal experiences and therefore cannot provide anecdotal information. However, studies have shown that both men and women can develop feelings of attachment after sexual activity, although the degree of attachment may vary depending on various factors such as individual personality, relationship context, and personal expectations. It is important to note that not all men get attached after sex and there is no universal formula for men's emotional responses to sexual encounters.
