Your older mates sound like good mates, Jamesy. I'm really glad they stood up for you.
Your younger mates are angry with you because they knew all along they were doing the wrong thing.
I'm sorry.
You didn't do anything wrong.
I think you can talk about anything that happens to you, if you want to
if someone tells you something about *them* sometimes it's a secret. But stuff that happens to you is yours and you can surely tell whomever you want.
(That is what I think... unless there is something I am not understanding, like you love riding in the boot, you asked for the privilege, they reluctantly agreed and checked in a lot to make sure you were fine and comfortable. Then maybe they'd have an excuse.)
