I guess i better start at the beginning. I'm still way nervous about writing this but here it goes anyway.
I'm not sure where the fine line between abuse and punishing is. It seems some people say hitting is always wrong and other people say you need to hit your kids sometimes.
As long as I remember our parents were into the last one. My mother not so much but she would tell my dad about it if we did something wrong and then he would hit us anyway.

When we were 3 or 4 he would just pull us over his knee and hit us a few times but when we got older he would also make us do other stuff.
He would embaress us by pulling down our pants and putting us over his knee to hit us when other kids were over up to about 9 years old.
He makes us drink a glass of soapwater or big spoon of sambal. He has a lot of belts and he either uses the one he is wearing or makes us get one and give it to him and then we have to take our shirt or pants off and he hits us with it. Same with making us get twigs or kitchen stuff like the big wooden spoons. He has ropes in the bikeshed too.
It always leaves bruises but no broken skin or anything unless he's drunk then he can't control himself. Thankfully he is not drunk very often. But theres not a week that goes by that he doesnt hit us all atleast once.
Most of it is done in secrecy, he doesnt want our mom to know most of the time. Now that im sick he dont hit me as much but now my twinbrother gets most of it I feel really bad about that.
