Be honest, is it weird for a brother to have a crush on his sister?

I'm just gonna be very honest for a moment, I'm terrified to post this because I don't want to ruin my life, I don't want to be judged, I don't want to be frowned upon, and I don't want to be told I'm disgusting. As silly as this is, I think every man has been attracted to his sister at some point in their lives.
