I'm too curious to stay with the same person forever
Why can't you be with someone forever?
I get bored and want to experience other people
If you cannot be loyal and faithful to one person then it is wrong for you to be in a relationship. You need to control your urges to cheat, seek counseling to find out why you have these feelings and thoughts.
Nah, I'm feeling fine with my life
It's up to you if you want to spend you life drifting from person to person. You might find it more fulfilling to find one person to build a meaningful relationship with.
