I am a lesbian and I didn't had that phase so don't generalise please.
Also many of them became lesbians not because they were attracted to women, but because they hated men so much, they must be into women.
Date them and you will see the lack of passion and attraction. Some can act, but even that facade cracks when you sleep with them. They were just straight girls who hated the fact that they were straight. It was a major improvement for them to make them admit that they were at least bi, but there is a lot of dishonesty among women concerning their sexuality and it was quite frustrating for me to get into a relationship, because most just wanted the status. They fucking used me for politics and privilege points.
