Unfortunately the man can not get pregnant. He could not give birth to children, he could not barest feed to baby.
And you yourself said in your Rishta thread:-
**I’m a woman. I dont need to work. YOU do. So, YOU pay the bills, the mortgage, etc. I DO NOT. I will fill in, of course, if you lose your job, get disabled, etc. But as long as you are healthy and able, you will not mooch off me. **
So you believe that man need be provider unless he lose the job or get disabled, i am sure the man would not mind to become househusband.
