trisher, yes, some women pay for sex. Recently, Lily Allen (pop singer) has spoken about paying for lesbian sex when she was on tour. She readily acknowledged she was in a bad place, living with anxiety/ depression/alcohol/drug abuse alongside a failing marriage and two small children. Needless to say, currently, she says she wouldn't want to repeat that behaviour.
SaraC, I mentioned up thread my contact with adults and children who were identified as sex workers. All had experienced abuse, neglect and trauma. All who had been assessed by psychiatrists or psychologists as having PTSD. Not much informed choice in them becoming sex workers. The notion of the happy hooker is nonsense imo.
