No, actually yours is. I didn't want to get into it, but part of being responsible in my opinion is letting your partner know that you're HIV positive. If the partner is willing to take the risk, and a lot of guys are, then what's the problem? Also, what's the problem with having sex with other HIV positive guys?
Also, you're assuming a 100% transmission rate if the condom fails, and that's just not accurate. I've heard a lot of different numbers, but 1 in 20 is the one that always sticks in my head, and it's a good enough example. So assuming that rate of transmission, the chance is not 1 in 100, it's 1 in 2000. And, you know what? That's just the risk you take if you want to be sexually active. Even if the guy you're with has a negative HIV test from the previous week, it doesn't mean he couldn't have contracted HIV that same week.
