No it doesn't. It is his life not mine.
While you will ostracize a gay son because he isn't good enough for you, I consider it to just be part of who he is.
Here is an example. I am divorced. My ex is a train wreck. I spent many years in a terrible marriage because of the kids. I see things in my kids that they got from her that are bad traits. I do not wish I never got married, or wish it was to someone else, because it produced my kids, and I would not want them to be any different than they are, because it is who they are. If any turn out to be gay, I will not wish they were different.
Your gay child will be stuck growing up as unacceptable to you, because you would be happier if he were straight. That is sad. And whether you say that to him or not does not matter, he will know. What child deserves that because of the sexual orientation they were born with?
