I have a fetish about another person drowning me holding me underwater

Hmm maybe I need glasses. I thought this said "I have a fetish about another person throwing me holding my underwear".

Hey, I've got just the solution to get your fantasy.
Turn yourself in as a terrorist and tell them you have information about an attack by several terrorist cells coming soon, but you won't talk unless you are tortured.
They will waterboard you, which is quite similar to your fantasy, except you can do it over and over again, which you can't do if you die the first time. Damn, missed that, didn't you?

Totally normal. I have a drowning fetish as well. And what you said about someone else drowning you, I wish someone would do that to me.

We could drown while we both wear life jackets!

Well, it could be a form of autoerotic asphyxiation. It can be dangerous, but if you're careful it's safe enough.

haha your friends could tease you (underwater) and pull yr shorts down
