Hmmm, not too sure what exactly to make of your post. I am a guy, btw. I don't see too much of myself in your post. I've always tried to be upfront and responsible with my own expectations.
But then again, can you really blame some hypothetical fellow for not wanting to be bushwhacked with news of a baby when least expected?
I'm not saying you or any other responsible woman would ever do that. But it's been known to happen with irresponsible women.
Maybe the men you met so far are not at the stage of their lives where they want a family yet, or even a girl friend looking for exclusivity.
Communicate with them your expectations and get them to communicate with you theirs.
