Of course there are straight men who have no desire to do anything with a man, period. Wishing someone is something they are not, because it is something you want them to be, is pointless, and often destructive. IF someone says they are straight, then accept it. Don;t try and make them something they don't want to be, even if they are--it isn;t up to you to change their lives for them if it even needs changing, it is up to them. I may compliment a straight man, and if he is a friend, I may tease him. But I do NOT hit on straight men, or expect them to change...just because some people believe sexuality is a choice, I don;t expect a straight man to change his sexuality, or be able to, any more than I am able to.
