Li has been active in calling for greater tolerance for nonconventional sexual activities in China. She thinks the country is undergoing a de facto sexual revolution, and encourages people to re-examine traditional attitudes towards sexual promiscuity and homosexuality. She proposes decriminalization of orgies and prostitution (both currently illegal in China). She also believes that monogamy is a personal decision made between a couple, and should not be enforced by law or social pressure.
As a member of the national committee of Chinese People's Political Consultative Conference, Li had submitted proposals to legalize same-sex marriages in 2003, 2005 and 2006. None have succeeded so far.
