Sorry, but this strikes me as crazy talk.
Not really. I was just being brief without a decent explanation. I don't like long responses. 
What criteria do you use to decide that you can "trust" some-one ?
What criteria do you use to determine that some-one is "clean"?
I've pretty much only slept with people I've been in long-term committed relationships with.
Naturally, I use sound medical tests. If I have any doubt or concern, I use a condom.
Do you ask to see the most recent HIV test? (Plus photo ID?)
Don't think photo ID is necessary for the people I sleep with. I only sleep with really close friends.
Do you just trust some-one when they say "I always have protected sex - BUT for you I'll make a special exception…."
I probably wouldn't. Then again, I don't do one-night stands.
Safe sex is wild, hot, horny, uninhibited, gritty, dirty sex. It's Sex with gay abandon.
And unsafe sex? For me it's the Big Turn-Off. I just can't do sex and be constantly worrying "Is this the time.....?"
That's your preference and I respect that. 
For me, I don't care if your HIV+ or not......just roll on that condom and Fuck Me Hard!
(And sorry, but I find the term "clean" kind of offensive. If we've gotta use anything, let's use HIV- please.)
I use the term "clean" because HIV isn't the only thing out there.
Trust me, my opinion is not without careful thought and consideration. So please respect that.
