Sex work is legal where I live. Nevertheless there is a lot of crime related to the sex work sector, human traficking, sexual abuse of minors, gangs etc. However I think it would be much worse if it was not regulated in anyway. My personal opinion - I would rather live in a world without it. Personally I would never go to a hooker. Most important thing though is that sex workers can decide for themselves and are not forced to do sex work (may it physical force, drug addiction or just no other way financially)
