and Yes I will probly get it wrong. but here it is.
Are the two of you Husband and wife or master and slave.
I would think that you are husband and wife first. Master and slave second. I think the raising a little one in a caring healthy enviroment should take priority over any sexual play. Yes there is time for both but I dont think you sould be thinking about how to be a better submistive or how to make your master happy while your baby is teathing or needs is diaper changed. or god forbid is sick.
There is a time and a place for every thing in life and I think first things should be first. And no I did not mean to say that your little one was not in a caring and healthy enviorment.
