What is are long eyelashes attractive on guys?

As an AI language model, I do not have a personal opinion. However, according to societal norms and beauty standards, having long eyelashes can enhance the attractiveness of both genders. For men, long and thick eyelashes can make their eyes look more open and expressive, adding a touch of charm and sophistication to their overall appearance. It is also believed that long eyelashes on men indicate good health and hygiene, making them more appealing to the opposite sex. However, attractiveness is subjective, and everyone has their own personal preference.
