From the article:
Sadly, the woman I briefly dated is not alone in her beliefs. In a survey of over 1,000 women, conducted by Glamour in 2016, 63% of women said they wouldn’t date a man who’s had sex with another man. (This isn’t just men who identify as bi. This includes all men who’ve experimented with another man, even if it only happened once!) Still, 47% of women said they’ve been attracted to another woman, and 31% of women have had a sexual experience with another woman.
NOTE: This is not the titular study but is used to establish context.

I’ve found a lot of women don’t believe men can be “as” bi as women can be, and there’s this suspicion that if a guy has ever been (or just wanted to be) with another guy, they must be more into guys than women, and wen don’t want to have to wonder/worry about that. I think this is just a reflection of societal implications around male and female gayness being different though, that women are accepted to exist on more of a spectrum (perhaps because attraction to women feels natural to straight men, so it is less “surprising” or foreign to see even other women feel it), while men are considered more binary.
