Spot on! One thing to add:

Sadly for a bisexual when they come out there’s always that element of “well, you can still be straight, right?”

There's also the issue that a lot of straight men (I can't say if it's the same for women) appear to be less threatened by a gay guy than by a bi-guy. I have no idea why, and I have no idea of the "logic" behind it.

Any thoughts anyone else might have on the subject would be welcome.
