when my husband wants to?", "What can I do to avoid getting pregnant?". By the end of the First World War, in 1913, Ottar met and developed a close friendship with the Swedish anarcho-syndicalist peace agitator . They married in 1931, and Elise Ottesen changed her surname to Ottesen-Jensen. When Albert Jensen was expelled from Norway, she came with him to Denmark. There, she gave birth to their child, who died soon after birth. Ottar and Albert moved to Sweden, and she came to know a doctor who amongst other things taught her how to use a diaphragm. She then set out for her first nationwide tour, in Sweden. She travelled from Scania to Norrland, teaching female workers how to avoid pregnancy. She agitated for the right for women to experience sexual pleasure, for free abortion, for the repealing of the laws against contraceptives, for gay rights, and more. What she did was illegal and she risked harsh penalties. In the 1920s, Ottar was a regular writer for Arbetaren, with her own column focusing on feminist issues. After a disagreements with the other editors of Arbetaren in 1925, she started her own paper, Vi kvinnor. The paper did, however, not last long. A few years later, she also wrote for the anarchist magazine Brand. In 1933, Ottar, together with a number of radical medical doctors and trade union representatives, founded the Swedish Association for Sexuality Education (, RFSU). She became its first president, and held this post until 1956. Ottesen-Jensen was also one of the founders of the International Planned Parenthood Federation (IPPF), in 1953. A paper published by RFSU bears the name "Ottar", to honour Elise Ottesen-Jensen. This paper changed its name to "Ottar" in 2001, and was earlier known as "RFSU bulletin". The name Ottar has also been used to name the Norwegian feminist group , who were officially founded in 2006. She was awarded the Illis quorum by the Swedish government in 1951 and honorary doctorate in medicine in Uppsala in 1958.
