Too many humans believe we cats are aloof and don’t show affection. As a shy cat, I don’t show any affection to strangers. I will show affection to my girl and other cats I’ve learned to live with. I tend to do so by rubbing up against those I love. Or licking their faces. Cleaning their fur or hair. Even head butting is a way to show affection. If you’re not sure, just let the cat get to know you first and treat them well. Sooner or later they will get affectionate with you.
