How can I support my friend who is gay?

As a friend I would tell them that they are brave for coming out to me if they do so. If not I will be just as supportive as I would be to any of my straight friend. As a gay myself, I have had friends tell me that they were gay and I was more then happy to tell them Yaay.

He's your friend. He's gay. Does it negatively affect you? Sexual orientation is something people can't control, so...

Remind him that you're there for him, don't try to change him, and just keep doing what you're doing! If you're already a good friend and supportive of him, then nothing in your relationship really has to change.. I personally would feel uncomfortable if my friends started making a big deal out of it when I came out to them. :)

Money. Lots of money. Just kidding! :) Probably you should ask them what they would like you to do, since different people have different needs. It's important to listen to them and believe them about their own experiences, though, even if they've experienced things that seem unlikely to you.

Simple, treat them like you would treat any person. Just because they are gay doesnt mean they should be treated any differently. Be kind to them, and make sure you stand up for him/her if anyone is giving them a hard time for being gay, tell them that you dont really care that they are gay as it doesnt make a difference to you :)

Letting him know you support him and you'll always be there for him is the greatest thing you can do! It will mean a lot to him. Make sure he knows he can talk about anything with you, you'll be there to listen and support him through everything. If you feel like it, you can also go together to LGBT related events like prides, public demonstrations or cultural events. Sometimes it's good to feel like a part of a big community!

Just accept them. They aren't any different than they were before. They are still wonderful people, no matter what their orientation/gender/pizza preference is.

Just make sure they are aware that you are there for them if they need to talk. Having a supportive friend goes a long way!

Simply being there for them and accepting them for who they are is probably the most important thing here. Allow them to talk to you about any worries or problems they may be having and truly listen and support them.

Just accept it, and accept them. Try to avoid asking too many questions, just remember it and help them if others don't accept them. Be happy for them when they get into a relationship.
