It isn't necessarily limited to women, though. I'm on the far side of my 30s and have yet to marry or have a significant relationship in years. (The one significant relationship I had with a girl left emotional scars on me which took very long to heal, so I take things VERY cautiously now.)
I've already gotten used to the idea of 'no wife, no kids, no hurry for either', but that doesn't make me a confirmed bachelor. Eventually I'll settle down, get married and maybe start a family, but as I've already told my old man, 'don't hold your breath waiting for grandchildren!'
