The lead singer of the band Against Me! -- famous for their hit "I Was a Teenage Anarchist" -- tells Rolling Stone he's becoming a woman ... but he's NOT attracted to men.
According to the magazine, 31-year-old Tom Gabel says he has a condition called gender dysphoria ... just like Chaz Bono (except in reverse) ... and has questioned his sexual identity since he was a kid.
Tom says he will take hormones and undergo electrolysis to help his transformation into a woman ... and is considering undergoing surgery to aid in the process.
Gabel tells the magazine his new name will be Laura Jane Grace.
Despite the transformation, Tom says he's NOT attracted to men ... and will still be married to his wife ... with whom he shares a 2-year-old daughter.
