You'll probably notice that nobody around here has left an email address (with the exception of advocates and sexperts), there's a reason for this. Email addresses are not posted, or exchanged simply for the safety of our users. So chances are you aren't going to be able to get in touch with him.
As far as not being able to reply to a post, that probably means it was either in Ask a Sexpert, or in a section of the boards that is now closed.
