A woman who negotiated a year-long 'open marriage ' with the husband she 'd been with for 17 years and took the chance to sleep with 12 strangers has opened up about her wild year . Robin Rinaldi , 50 , had always considered herself a 'good girl ' , but ended up being so transformed by what she referred to as her 'wild oats project ' that she left her husband after the 12 months ended . Rinaldi , who lives in San Francisco , had previous slept with only four men including husband Scott Mansfield . 'WIld oats ' : Robin Wright , 50 , negotiated an open marriage with her husband of 17 years , which allowed her to bed 12 strangers in 12 months - which ultimately broke her relationship . But during her year of abandon , she bedded ten men and two women , whom she picked up online , in bars and at sex classes . She made the life-changing decision to pursue sex with other people in 2008 - and has written a book about her exploits called The Wild Oats Project . Rinaldi described her relationship with Mansfield , a brewer and wine-maker , as 'stuck in a rut ' , adding that 'our once-a-week sex life was loving , but lacked spontaneity and passion ' . But she decided to make the change after begging him for years to have a child with her , and finally realizing that he would n't after he got a vasectomy . Struggle : Wright said her husband , Scott Mansfield , right , was loving and dependable - but did not share her desire to have children , driving her to want lovers instead . Reliving the fraught decision in her book , she wrote : ' I refuse to go to my grave with no children and only four lovers ... If I can ’ t have one , I must have the other ' . Under the terms of her new deal , Rinaldi took out an apartment , where she lived from Monday to Friday and would bed her conquests . But over the weekend she would go back to Mansfield , and the two would live as a married couple , without asking what the other had been doing while they were apart . Initially , the two agreed not to sleep with mutual friends , get into any 'serious ' relationships or have unprotected sex - but ultimately failed to stick to them . Rinaldi wrote how she started out by posting an online ad , entitled Good Girl Seeks Experience . In the post , she wrote : ' I 'm a 44-year-old professional , educated , attractive woman in an open marriage , seeking single men age 35-50 to help me explore my sexuality . ' Account : Rinaldi describes every step of the 'project ' in intimate detail in her newly-released book , The Wild Oats Project . The next day , she had 23 offers , she recounted to the New York Post . Her first encounter was a 40-year-old lawyer , whom she bedded in her apartment on the second date . Describing the night , she wrote : 'We stumbled to the bed , where he turned me onto my hands and knees and took me from behind . 'We had intercourse twice and , after he left , I felt satiated . ' She later moved on to much younger men , and described texting her husband goodnight from a Las Vegas hotel room moments after a 23-year-old paramour left the room . Two of her 12 encounters were with women , one of which was a threesome . Describing another encounter , she writes explicitly about taking a new-found pleasure in fellatio . In the extract , quoted by the Daily Beast , she wrote : ' [ penises are ] beautiful… I took pleasure in mastering them from up close , watching them expand and harden , tracing the ridges of their warm architecture against the roof of my mouth . ' However , after the raucous year , Rinaldi admitted , she could not turn back . Attempts to rekindle their marriage after the year failed - and Rinaldi began sleeping with one of the men from the past year , whom she refers to by a pseudonym . She wrote : 'The turning point was hearing from Alden . He sent me an e-mail , out of the blue , several months after the project had come to an end . 'Before long , we were having sex again . Being with him was exquisite . After reconnecting with Alden and falling deeply in love with him , there was no going back . ' Irretrievable : After Rinaldi 's year of uninhibited encounters , she was unable to rekindle her loving marriage with Mansfield , and the two now have different partners . Rinaldi has now lived with 'Alden ' for five years in a monogamous relationship , while Mansfield has also moved on . The former couple now consider themselves at peace - and Mansfield was even happy with her writing the book , detailing every aspect of their sex lives and her previously secret exploits with other men . Speaking to the Daily Beast about how he responded to the book , she said : 'His response was , `` You have to write it . If you write it well , it won ’ t really be about us , it will be about lots of marriages . '' '
