Yes, they do.
Men, women, couples, boys, girls, people, male, female, gender-neutral, young, old, ugly, pretty and all other types of humans are all wearing promise rings.
So if you are a boy or man don’t let anybody tell you otherwise. Promise rings are there for everybody.
It’s usually given by one lover to another, but friends and family members also order promise rings for each other. And you can surely order one for yourself if you want to. As a great reminder to that promise you made to yourself.
