I used to be close friends with one for years. It depends on what you want in a relationship. If you want fun, being spontanious and doing things, good. If you want a lot of depth and a long serious lasting relationship, not so good. Even though I guess, even ESFPs do change a bit when they get older when it comes to the lasting of their relationships. My friend jumped from guy to guy for years. But then she finally had a relationship that lasted several years.
