I'm with Nicoli on this. Whats the point of the OP!? He's not exactly warning anyone of any specific risk people aren't already aware of (like a specific individual, etc.). He had a scare and is saying goodbye to punting. But he consented as an adult to have unsafe sex, and he rightly stated that we all need to take responsibility for our own actions. Tarnishing all the working girls with one brush is just totally unjustified. It's their profession, it's in their vested interests to remain healthy. Although I'm sure some offer unprotected session, I bet there are a HELL of a lot more punters requesting it.
That aside, I'm glad he is healthy - and of course, saying NO to unsafe sex should always be celebrated.
