@JGoldman10,
I wish you would answer the question about whether "admiring their beauty" is sexual or not. It raises in interesting dilemma.
If it is sexual to admire the beauty of someone, then I think we would agree it is lusting.
If it is not sexual to admire the beauty of someone, then whether the beautiful person is man or woman wouldn't matter. It can't be homosexual if it isn't sexual.
I guess there is the possibility that looking at men is a sexual act for you, but looking at women isn't. But that would be a little weird even for you.
