I am bisexual in a long term relationship with a man, but it has been an open relationship. My therapist is straight and monogamous. I have at times had some points when I didn't think he got it, but nothing significant. I feel more misunderstandings in general strangely enough in lesbian circles, where when dating women I was treated as suspect. A fence sitter or "anything that moves" type. I tend now to just not foreground the issue because I have come to believe that people probably won't understand and it is not worth introducing into the mix. I can usually tell if people are more open and then it feels good to share. My therapist has occasionally thought of me as lesbian I guess because I look the part whatever that means and when I corrected him he didn't seem to get why. But now it doesn't seem all that important.
