Friends experiment gay

Lots of gay guys at one time hooked up with a girl, but it doesn't mean they actually aren't gay. Same thing with straight men. Straight men end up experimenting with other guys for all sorts of reasons, but it doesn't change their underlying orientation.

young guys experiment with one another. it's perfectly natural, and nothing unusual about it. if you enjoy it, just go with it. no need to overthink things at this stage. what you will do and how far it progresses is up to the two of you. don't do anything you don't want to do.

He told me that my best friend struggle with gay feelings for a long time, but he claims that god "fixed him". So right now I'm just really worried that he's suppressing his feelings and I don't think that is good for his wellbeing.

I (male) had my first gay experience when I was around 12 years old. It was with a friend (also male and around the same age) and went on for two or three years.
