No I don't, but I think what it seems to show is that there is a small group of homosexual women, and then a larger segment of bisexual / heterosexual women who have some interest in other women. Like, I think there are loads of straight women who have labelled themselves as bisexual at some point, or have only had a brief / slight interest in other women. I wouldn't call them bisexual.

I think the point of the study though is to show that a lot of people experiment and try things as teenagers or young adults before settling into an identity that more accurately reflects who they are... so a lot of people who might've called themselves bi or lesbian as a teenager probably weren't. I can't tell you what the study means by the fact that most people in the "bisexual" group were no longer bisexual because I can't read the study itself either (like, how did they define bisexual?)... But from what I can see they are grouping together the women who have primarily have sexual experiences with men but also report some level of sexual attraction to the same sex in their teens or 20s, but whose attraction to other women doesn't remain as they get older. I think they want to make this group distinct from bisexuals who have continuing interest in both sexes and homosexual women who are gay from woe to go.
