This is a frank post so skip if you don't want to read very frank talk.

I agree with everybody else- cancel the meetings! Back a year or so before I was diagnosed, I went through a (long) phase of meeting people from dating sites and having random sex. Sometimes in hotels but once in the back of a guy's truck and another guy's car- WITHOUT protection. Yup. And I fear that you are headed down the same path- and quickly. I got lucky- I was never hurt or got a lasting STD. But I did get bacterial vaginosis from sex with one of these guys. That's a bacterial infection that can only be cured with a gel medication and its very difficult to treat. It itches like crazy! Worse than a yeast infection. So I didnt get an STI proper but I got an infection from sex so yeah it was an STI. PLEASE CANCEL THESE DATES/VISITS/GET-TOGETHERS. I got lucky I didn't contract HIV. You don't know that you will dodge a bullet too- and there are many.
