Although I have had great experiences on both sides with some great lovers and friends accepting that is something entirely different. At moments it can be ok but for the long term? I just don't know. Living life is so much more difficult than thinking about it, I know that might sound kinda dumb but its true. Living as you feel takes courage.
I physically enjoyed my relationship with my friend but it doesn't really lead to where I want to be. It is/was good for filling the gap (no pun intended) a pleasurable care free experience but it isn't everything. Which is why I describe myself as bi but significantly more straight than gay. I enjoy getting fucked and sharing sexual experiences with some of my good buddies. I care for him as a friend but the whole relationship experience, romance and the total mix is only satisfied in a relationship with a female. Think I'm migrating towards that now maybe.
Bi as you may (be), society makes personal satisfaction and completeness difficult to obtain.
Not sure though so input is welcome!
