I think it's a matter of personal preference.

I married at the age of 25 and it was perfect timing. I wouldn't want to have married any sooner or later. I also wouldn't want to change who I married or the fact that I married.

But I am open-minded. There is a chance that out of the 7,442,000,000+ people living on earth, one or two of them (maybe more?) might experience more happiness and fulfillment by remaining single as opposed to getting married.

You might want to consider that a possibility too.
