Tell him you like something specific about his appearance, such as his eyes, his smile, or his physique.

Avoid compliments that are too sexual or suggestive. This can make him feel uncomfortable or objectified.

Also, avoid comparing him to other men. This can make him feel insecure.

When complimenting a man on his accomplishments, be specific and sincere.

Tell him how proud you are of him for something specific he has accomplished.

Avoid compliments that are too general.

 For example, instead of saying "You're the best salesman in the company," tell him how much you admire his sales skills and his ability to build relationships
