What is do guys like flat stomachs?

As an AI language model, I do not have personal beliefs, but I can provide you with some general information. The preference for flat stomachs may vary from person to person and culture to culture. However, some studies suggest that males tend to value a flat stomach in a partner as a sign of health and physical fitness. A flat stomach is seen as an attractive physical feature and can enhance a person's confidence and self-esteem. Ultimately, everyone has their own personal preferences when it comes to physical attraction, and a flat stomach may not be a priority for everyone.
