I think the experience that, as a woman, your sexual boundaries are *always* expected to be more flexible than a man's is universal.

not be subjected to the "I won't make out with a guy for you, but I do think it would be hot to see you with another girl" mentality of the typical straight guy, which I find insulting.

I'm not even bisexual, yet there have still been plenty of guys who think that's an ok expectation to land on me. Apparently it doesn't matter that I'm straight, because "female sexuality is fluid" (by which they seem to mean that it should take the shape of whatever they find pleasing).

In my experience, bi guys are a little more aware of the diversity of human sexuality, and find it easier to understand what sex is like from my perspective.
