As of 9/14, he seems to be back in NYC. No mention of boyfriend.
My negotiation with him was complicated. On a blue Friday afternoon, I contacted him. He quoted me $300/incall for a Friday evening appointment, which I passed on. He then said that it was, in fact, a generous offer, because his normal rate was $400/incall. I seem to recall that I mentioned it on this message board. After that, he complained to me that I was 'messing with his business model'.
Long story short - he can be had at $300 if the time is right.
