By Mary Papenfuss SAN FRANCISCO (Reuters) – The head of San Francisco’s Erotic Service Providers Union has been a sex worker for 24 years — and “I hope to be doing it for another 24,” says Maxine Doogan. But she dreams of a future when she won’t be treated like a criminal and could earn a little respect in the city that launched the fight for sex worker rights 41 years ago. Calls by Bay Area sex workers for decriminalizing “consensual” prostitution have been spurred anew following the FBI seizure of a West Coast sex services website that prosecutors say hooked up clients with prostitutes and which sex workers saw as a vital forum to screen dangerous clients. The shutdown in June of website myredbook.com left local sex workers scrambling for business and worried about their safety.
