I don't believe that is her point. I believe she is saying that she didn't choose which gender to be attracted to sexually. Did you choose to be sexually attracted to members of the opposite gender, and conversely, sexually repulsed by those of the same?
I agree with you, that is what she is saying.
Did you choose to be sexually attracted to members of the opposite gender, and conversely, sexually repulsed by those of the same?
Without going into gory details, yes. I find the thought of kissing a guy extremely repulsive. Could I choose to be the other way, or both ways? As a happily married man, I have no reason to, but I certainly know people who have.
