They may like it, but extroverted people are less likely to put a ring on it.

Dr. Tomas Chamorro-Premuzic, Hogan’s vice president of research and innovation, and his colleagues surveyed more than 16,000 people to examine how personality influences relationship style. They found that extroverted people tend to be more passionate in their relationships, where conscientious people tend to favor intimacy and commitment. Agreeable individuals tend to be intimate, committed, and passionate.

They also found that two out of three relationship styles were significantly related to how long a relationship lasted. People with a committed relationship style tended to have longer-lasting relationships, where passionate relationship style was negatively related to relationship length. That is, if you tend to be more passionate, your relationship is likely to end more quickly.
