I was threatened and milked at age of 12 years, is it normal ?

I was born and brought up in a poor family in a Asian country, and I lived in a very rural village, with no electricity, water supply or anything. Later my mom was got married, when I was 12 years old, once in a summer we went back to my uncle s house ( my mother s brother s house), it was summer days, also it was a rural village, we used to belongs to a lower caste in the village.

One day, two women ( around 30-32 years old) from a rich upper caste family came to my aunt s house, they told that their milkman had not come and their cows are remained un- milked today, and they were wanting help to get their cows milked, but because they belonged to a upper cast family, and my aunt and mom were from lower caste family so they were not allowed to go their home.

And only my mom knew how to milk a cow, so my aunt got a tricked, he called me and asked me to strip down quickly, I was 12 years and did not want but I was threatened, and I had to strip nude and I had to go on my knee, than my aunt asked my mom to teach those two women, how to milk a cow using my penis, at first my mom hesitated but later she started milking my tiny dangling penis like it was a real udder of a cow, it was a painful and embarrassing experience.after this incident whenever any relative visited to my house, either my mom or aunt used to tell this incident to them like it was a funny thing which was done to me and most of the relatives made fun of mine so this effected me badly And still has very bad effect on me but no one ever said any sorry or apology to me and I don t have normal relations with them,what do you think about the behavior of my aunt, mom and family, what do I do?
