Alice Frohnert was a sex worker for more than 15 years. She is far from finished with the trade – with love and men she is.

Sometimes the men just wanted to be tied up and beaten. But mostly they wanted sex. Alice Frohnert, then 22, did what she was paid to do. More than 15 years. Then she had had enough. As much as her clients craved wild sex, she craved an intellectual challenge. So, in her mid-30s, she caught up on her degree in communication science in Berlin, did her doctorate and wrote a book about prostitution. The 57-year-old now works as a journalist for a small Luxembourg daily newspaper. With the star she talks about her experiences with unfaithful men and marriage and explains why we should all be a little more like Heidi Klum.
