In most prisons even masturbation is against the rules.
Personally I think that is a bridge to far and they should have a masturbation room.
If you think prisoners should be able to inmate sex and orgies. Write you state leaders as they can change the laws.
The problem is many people don’t care about the incarcerated. I want prisons to keep dangerous people away from society and rehabilitate those who are returning to society. I’m not a fan of prison is punishment since that doesn’t really fix anything
