Yup. Bisexuality is highly fetishized in the poly community. I hate it I hate it I hate it.
I love how you articulate your exploration, and your oppenness. As long as it was true to what you really desired! I hope that much for you. What a beautiful experience it can be to discover yourself in this way.
I hope it was not inspired by the pressure from dudes who get off on sexualizing the existance of queer women. A lot of women in the poly community feel the need to perform bisexuality in order to please others for these reasons.
Then again, even if this pressure did inspire your exploration, it led you to a wonderful experience.
