Why do mother suck on baby penis?

Answer 1

I did do it with my daughter and son when they were babies, for her until she was 4 years old and for him at 5, we stopped doing it because they wanted more and more, but nothing happens anyway, as a mother I can say that I liked it enough to make them feel good

Answer 2

In some parts of the world, mothers seek to stimulate that part of their babies anatomy in the belief that it will help them grow up to be manly men. That's how I understand it. I assume that you are from that part of the world. Although I've lived in that part of the world, maybe someone from your part of the world or from your culture could improve on this answer.

Although such stimulation is an accepted part of nurturing a male baby over there, it would cause big problems over here if social workers were to learn that it was happening in a U.S. home.
