Connection to sexuality
Yes, indirectly. Cool can imply sexual attractiveness when describing a person’s style, attitude, or aura (“He’s a cool guy,” “She has a cool, sexy vibe”). In slang, being “cool” is tied to confidence, which often overlaps with sexual appeal. However, its main uses are broader: calmness, fashion, or approval.
