Bro "lesbians" don't exist, people have to stop spreading this myth like that would even be a thing that works.
In order for two people to be sexually involved one of the parties have to have initiative, and women don't have initiative, they just go along with whatever other people are doing. Therefore the only two types of lesbians are young straight women in denial, and asexual dykish cat ladies looking for a roommate buddy.
Go ahead and ask your average steady lesbian couple when the last time they had sex was. I'll bet it's been years, since they figure they've reached a point where they don't have to keep up the act.
The whole thing's an obvious sham that people just go along because it's the polite thing to do and these..."lesbians", as you call them, will get offended if you say you think they're all full of it.
This "Kate Harris" lady you're referring to is a liar and a charlatan.
