This story happened about a week ago but I was too embarrassed to say it

So basically I was taking a shower and messing around with my junk, not for pleasure just kinda poking at it at such, and I grabbed foreskin and held it up like someone would hold open a trash bag. I let the water fill up like it was a mini shot glass and then let the water drop. This gave me the brilliant idea to try to drink the water out of my dick like a cup came up.

The next day, ready to try my idea I brought a straw with me to the shower. I made sure to wash thoroughly, beforehand to not make my experience bad.

This is probably the time to mention I’m not the kind of person I do not piss in the shower. Not that I’m against it, just never really did it. But I was ready to drink from my new cup so I got the straw and held it in my mouth setting up my cup. And so I held up my foreskin above my dick like a trash bag. I let the water fill up the room and stuck the straw in there and began to drink very slowly(I was letting the water fill up as it went in or else it would’ve emptied too fast). As I was doing this I accidentally stooped my head too low and scratched my dick against the straw which hurt immensely and for some reason, my body reacted to this by peeing for some reason and. so I accidentally drank my piss because I was too slow to react to what happened to me.

After my body understood what happened I immediately started freaking out. I spit the straw out of my mouth and fell to a vertical fetal position on the ground. I Kept on using the water from the shower to rinse my mouth out and moaning in pain from my scratch.

Tldr tried to make a cup from my foreskin and ended up scratching my dick as well as drinking my own piss.
