Lipstick Lesbian Identity

I am intrigued as to whether there as been any academic study/research on the lipstick lesbian identity. Have researchers surveyed women who identity as lipstick lesbians? Have researchers discussed how these women experience and express their sexuality or issues such as harassment from heterosexual males or the assumption that they pass as heterosexual? I have read a few blogs and websites regarding this identity and these issues, but I have yet to see any papers. I am going to dig further.
