Light commitments are those which express a compatible bond and respect for each other. It can be demonstrated by exchanging class rings, jewelry, gifts and or remaining faithful. Being faithful includes loyalty to one's partner and not dating others. More advanced dating stages involve putting the other's needs above the importance of one's own, but this rarely happens in high school. This type of dating is not a model case.
Some teenagers date multiple partners.
They could do this for experimentation. Teenagers have to find out what they want in a relationship. They find compatibility and levels of commitment that satisfy and suit them. Other teens date without sincerity. They date only for pleasure and excitement.
