What have we learned?
1/ We can all agree CBJ is less dangerous than BBBJ
2/ Abstinence is safer than any kind of sex.
If you're going to partake in BBBJ, some common sense could help. One thing I like to do is to see SPs who are working limited schedules. The greater than number of sexual partners the greater the risk. Even an SP working twice a week and seeing three clients a day has 6 sexual partners per week, that is significant. Now imagine some backpage provider who get a room and sees 7 in a day, maybe 10. We're talking an exponential increase in risk. I'm sure most SPs would ideally find a small number of high-income regulars who get multi-hour appointments. That minimizes risk and is also probably less emotionally taxing than the prospect of a perfect, usually unattractive stranger at their door ever hour and a half with obscene expectations who is going shittalk them on the internet if they can't make him feel like a 10 inch superstud. That said, realistically most SPs aren't going to achieve such an arrangement. Therefore, you, as the hobbyist, have to exercise reason and judgment that perhaps a 19 year old SP wouldn't.
I only get hankering to do this every month or two anyway, and only when I'm single. These guys that see at least one per week astound me. It's risky and expensive. Don't know how you justify it either way.
