Men are the powerful ones I often hear. We men are the ones that get all that we want. And that may be true in some domains, but not all.
Men do not get the right to be a parent without the consent of a woman. (The exception is via rape and this is rightly condemned. However, note that in this case, conception depends on the vagaries of nature first, and then the woman's choice second. In the modern, Western world, abortion is generally available on demand, especially if conception was via rape).
Once a woman consents to conception, it is interesting that she gets all the congratulations. Everyone comes up and rubs her tummy, smiles and says well-done. No-one is rubbing his genitals and saying 'well done'!
In the first instance, men need a woman's consent to contribute to conception. They must then hope like hell that they were the only one invited to contribute. Apparently their hopes will be for nought in some minority of cases.
In the second instance, he needs her consent to be allowed access to the kids, and still hope like hell that he was the one that contributed at conception!
