She addressed the controversy about her sexuality in the song "In or Out" on the album Imperfectly (1992). However, in 2015 she told the blog GoPride.com that she was ""not so queer anymore, but definitely a woman-centered woman and just a human rights-centered artist." In a 2019 interview with Jezebel, she stated that she preferred the term "queer" because "bisexual" "always sounded very medical, like something you do to a frog in 9th grade science or something", and further added that "the irony is I’m pretty fuckin’ hetero, which is unfortunate for me because many of my deepest connections are with women. But, naw, I just like what’s in boys’ pants better.". In 1998, she married her sound engineer Andrew Gilchrist in a Unitarian Universalist service in Canada. DiFranco and Gilchrist divorced in 2003. In 1990, she wrote "Lost Woman Song", which was inspired by her abortions at ages eighteen
