I don't know how personal this poem is to you, but I'm sure this is reality to some, so I feel like I should treat it as a personal thing.
I may not be the best suited person to comment on this topic, because when on rare occasion I actually have a crush on someone, or something along those lines, I tend to unabashedly admit it, with no concern for that persons gender or sexual orientation. I honestly don't think it matters; rejection feels the same regardless.
But this is about acceptance, I think(?), and as I just explained, I'm not inclined to be concerned about that, but I still feel the priorities are a little messed up. Of course, that's not something I could blame anyone for, except for maybe saying that something is wrong with the world in general. In the end, I think the only thing that matters is whether you can accept yourself for being who you are. Some people will reject you, some will even hate you, but that kind of contempt is something that pertains to anything remotely different from the norm; it's not limited to sexual oriontetion. The moment that kind of hardship becomes unbearable, is the moment you let it get to you and actually start believing that something is wrong with you. On the other hand, if you can accept yourself for who you are, that kind of hardship becomes a test of courage that ultimately will strengthen your resolve and leave you with a greater feeling of achievement. I think. Sorry, that was kind of a long ramble.
Anyway, the possibility of rejection comes later; first is acceptance of yourself and your own feelings. Gender doesn't matter in that equation.
