I would say it really depends on where you are in life. If you like going out and meeting new people for sexual exploration then being married is not for you just yet. Even if you are currently in a monogamous relationship. There should not be any temptations that you truly consider.
If you like being committed to one person, and are willing to put in some great effort for a relationship to truly work then I think you should consider marriage. I am coming up on my third wedding anniversary and I can't wait until we see our 50th! Personally, I love the stability and getting to be with my best friend every single day. I love being married.
