Yes, a guy can find a girl who is 11 inches shorter than him attractive. Attraction is a complex and subjective aspect of human relationships. Physical height differences are just one of many factors that can influence someone's attraction to another person.
Some individuals may have preferences for partners who are similar in height, while others may be drawn to partners with noticeable height differences. Ultimately, what matters most in forming a romantic connection is mutual respect, shared interests, personality compatibility, and emotional connection.
People have different tastes and attractions, and there is no universal standard for what makes a relationship successful or fulfilling. As long as both individuals are happy and comfortable with each other, height differences should not be a significant obstacle in forming a loving and meaningful relationship.
