Prostitution and prostitute.
See how the word play and rebrand to "sex work" is to make it more respectable and hide the pimps who profit from selling others.
OF is still a prostitute providing sex acts for pay.
Breath play is one person assaulting another.
Grooming in CSA is all about making the child believe that they are saying yes to a sex act.
A TRA was happy to go on camera to say that if a child said she/he was not harmed by the sex act then the TRA would believe that to be true. A child who has been groomed will believe that having sex was not harmful and therefore she/he would not be harming another child by having sex with them in the same way.
Would you accept the TRA's conclusion or say that the childs understanding of harm is flawed.
