Why am i gay?

That's a big question, mate. The real answer is, no one knows for sure one single reason. Most scientists reckon it’s a mix of things. Like your genes and other biological stuff. Stuff that happens even before you're born. It's definitely not a choice. You don't decide it. It's just a natural part of who you are. A bit like having brown eyes or being left-handed. Try not to get too stuck on the 'why'. The most important thing is just accepting it and being happy with yourself. It's all good.
