You can't.
I've been very kind and kept my cool answering dumb questions like this. I don't like being mean, I'm not that kind of guy, but why would you ask something like that? You cannot get your son to stop being gay, he was born that way, nothing you say or do will change that, okeh? I honestly feel bad for your son for not having tolerant parents or at least two parents who support him, I'm not sure on your spouse. He could have kept it secret from you until you absolutely had to know.. You should feel happy he loved you and trusted you enough to tell you. This question disgusts me... I wish your son luck and I hope you will accept him someday, and provide the support he needs from you.
It could just be a phase...a lot of people who claim they're gay/bisexual/lesbians this day and age just say it for attention and don't really mean it. It's so wrong but it's very common.
You can't, they are what they are, there's a science to being gay, it shouldn't matter anyway, there's nothing wrong with it.
I haven't been on here or social for almost two weeks... And this question was the first thing I see. You can't change your son, there is nothing wrong with him. Gay isn't a disease, he's still yours and you should love him.
Haha, this question is funny, you are joking, right? If you're serious, you have a lot to learn my friend! I'm bi, I lean more towards guys tho and I have a boyfriend. My mom isn't too thrilled (huge Christian) Dad is cool with it. Even tho my mom knows she can't do anything, she still loves me just the same and knows I will not change. ;p
You have to solve the magic equation and then, just then! It still wont work.. He'll always be gay, honey.
You can't.
With all the awareness out in the world today, this question surprises me. I refuse to believe that you don't already know the answer.
Move your family to a place with less attractive males. Maybe somewhere with the worse dental care and high obesity rate.
Sorry, but there's nothing you can do. It may just be a phase that he's going though, but it may not. All you can do is accept it and love him the same.
A fair number of people I've come into contact with have claimed homosexuality because it makes them more popular, or in their words, "it's the thing right now." This could be one scenario.
The other is that your son is actually a homosexual, and you can handle it however your culture/religion dictates. But to get him "to stop being gay," or cease finding other men attractive isn't a thing. Attraction doesn't really work like that.
