I get ballbusted by my sister?

I born in a feminist family. I have 3 sister, 1 older and 2 younger & they all are ballbuster. they hit (kick, squeeze etc.) my testicle in cause & causeless. My mom allow it, sometime take part with her daughter. Sometime they bust my balls so hard.
WHAT SHOULD I DO NOW?

My mom say, It is painful for a short time to me. But it is very helpful for my sister to live confidently.
