Transgender activist Jennifer Finney Boylan explains that she is married to a woman but only one of them is a lesbian.

Boylan, 54, the author of She's Not There: A Life in Two Genders, the first book by a transgender American to become a bestseller, currently teaches English at Colby College in Maine.

During an appearance on cabler Current's Say Anything, Boylan discussed the difference between gender identity and sexual orientation with host Joy Behar.

“It's not who you're in love with, it's who you are. Or, if you like, it's not who you want to go to bed with, it's who you want to go to bed as,” Boylan explained.

“So, did you become a lesbian then?” Behar asked.

“Yeah!”

“The woman that I sleep with is the woman that I'm married to.”

“But you don't consider yourselves lesbians, somebody told me.”

“So, my wife, who married a man identifies as straight,” Boylan explained. “She still identifies as straight but she's married to me. So, here's 2 women legally married who are not both lesbians.” (The video is embedded on this page. Visit our video library for more videos.)
