Is there any good fortune to be born casually by a young girl?
Of course the girl will love you, perhaps even more that an grown up lady will do.
Of course you will receive even more attention and nursing by grandparents.
You WILL be a lucky guy, I believe.
But will your mother 20 years old get happy when she is 30-35? When you will
need less her attention, and she will feel herself lacking young boys glancing her back.
Anyway it is her business, but if you are a smart guy no chance to be conceived
can be allowed by you!
