Wow! This is really an all "black-or-white" crowd today!
Managing risk in your life is rarely an all-or-nothing thing. For example: driving is mortally dangerous. Is the solution to never get in a car? Of course not, only the most neurotic among us would think that. Rather, we wear seat belts, buy cars with air bags, etc.
Same decision when punting. The risk cannot be reduced to zero (unless you count jacking yourself off from across the room
) but we can manage it to whatever level we're comfortable with. So you do or don't wear a condom, you do or don't let the girl give you a BBBJ or DFK, you do or don't DATY, etc. Maybe you don't even punt simply because you know you can't trust yourself to put on a rubber.
A testing regime is also a reasonable addition to include. If you believe that safe hobbying is about: 1. not catching anything, and 2. not GIVING anything, then certainly testing is important. If you also want to use testing to reduce your own risk of catching disease, then you can research the home and instant tests as well as the local clinics (search for Irishdog's posts on the subject, he states some experience in taking girls to the clinic at the start of a weeklong frolic . . . interesting first date, no?
)
I remember seeing a 20 minute cheek swab test on the market in Singapore a couple of years ago. I won't comment on its efficacy, research it and talk to an STD pro. A "mail-it-in" test doesn't sound like it will fit your purposes.
And, lastly, I find it helps my decision making process to put some numbers on the risks. We all fall into the bad habit of not doing this and this leads to the "all or nothing" kind of discussion which is not helpful. For instance, in the U.S. the prevalence of HIV infection is 0.5% (estimated) of the total population (300mm), what does this mean in terms of prevalence for working girls and sexually active adults (a subset of the total population), and how many partners must a WG (or you) see before you statistically likely to bump into an HIV+ partner? What are the estimated rates of transmission? All of this, I find useful for thinking about managing the risk in this hobby. Others may disagree, but do what works for you.
