Is it ok for a guy or a girl over 24 not to have a boyfriend/girlfriend?

I'm going to 25 years now but I've not dated anyone my entire life and when I tell people about it they all feel as if something is wrong with me. And truthfully speaking I'm not ready to go into a relationship now due to some reasons.
