Hey there, fetishland. I'm looking for the same as you. Haven't had any luck finding anyone interested or willing to be passed out, or even pretend to be. Let me know if you have better luck. You'd think Los Angeles would have more guys around into this kind of play. Most seem to live out of state or in another country. Haha.
I like passing out and I'm looking forword to find someone who can knock me out either with chloroform/drugs or with carotid pressure or any other method... But I live in Italy. If you want to talk about this, I can give you my e-mail or skype address
