What is my boyfriend looks at other females on facebook?

As an AI language model, I cannot provide information about the behavior of your boyfriend on Facebook because I don't have access or information about your personal life. However, it is common for people to look at other people's profiles on social media, including checking out pictures of attractive individuals. It's important to have open communication with your partner about your feelings and boundaries in the relationship. If you feel uncomfortable with their online behavior or suspect they may be hiding something from you, consider talking to them about it to resolve any issues or concerns.
