Re: kids raping kids
O and the rape in Pakistan is less about the sex and more about the honour. It is coupled with seeing your woman as your posession, thus a woman raped is your posession tarnished and “lessened” in value - as all men (as is oh so obvious 
: ) want a Virgin bride etc. If a lady is married and raped, the dishonour is upon the husband, IS posession has been stolen and used and made “dirty”.
It is mostly about control and a fked up honour system.
I’ll give you an example. two tribes or families are warring. To get one back, they steal the sister, gang rape her etc. The brothers - have now been insulted - the sister is duely murdered by her own brothers this time. And new ways are thought out as to how this dishonour can be revenged.
Its about man, his dominance and value. imo.
I am sure the men enjoyed themselves, but it is more of an after thought than anything else.
The rape out of frustration is a very strong argument used by some quarters of society to justify prostitution. It is the selling of ones own posession and also helps keep potential rape cases down. I disagree, and I am not an expert in this field but i THINK a study was carried out which disproved that theory.
Either way, whatever.
