Is AUTHOR wrong in the post ? POST : TL;DR: Friend took a photo I didn't want circulating. Wrestled him to get his phone and delete the photo. In the process, his phone microphone stopped working. AITA?

Before we get started, two pieces of pertinent background: 

1. I'm in college and last year when I was showering, one of my friends (Mark for the story) took my clothes in the communal bathroom and would only give them back when I shouted, "I DO BUTT STUFF WITH MEN." (I'm a heterosexual male.) He recorded it and sent it in a ton of groupchats, repeatedly played it in coffee shops, and was generally obnoxious with it.

2. I have really bad hyperhidrosis (excessive sweating), so once a week, I have to use a very strong antiperspirant before I go to bed. It stains stuff really badly and has left dark smudges on my sheets. It's annoying, but I don't mind them, even though they look like cum stains.

Fast forward to Friday night. Mark comes down to my room and we're just chatting like normal. He spots the stains on my bedsheet and asks if they're jizz stains. I tell him they aren't, but he took a photo of them. I knew it was going to be a repeat of the "I DO BUTT STUFF WITH MEN" episode, so I launched at him to delete the photo (Wrestling isn't entirely out of the ordinary for us.) After about ten minutes of wrestling, I got him to unlock his phone and I deleted it. His phone took a couple hard hits, but nothing ridiculous and we thought nothing of it.

Today, Mark told me his phone microphone isn't working anymore and he wants me to pay for a new one. I was busy when he told me about it, so I said I'd be happy to discuss it this evening when I had time. We were in class together today and before it started he kept saying "kidneystoneslayer broke my phone" over and over really loudly, despite my telling him to cut it out and handle it like an adult. 

Am I the asshole?
