"How do these things affect the Epididymitis? Is exercising bad for it? Is ejaculating bad for it? Does drinking make it worse in the long-term? I am new to this and am trying to figure out what my outlook on these things should be"...

Well, hate to say this, but welcome to the club. My own perspective on those questions is firstly, exercise in itself is hardly ever bad, but my point is if you are suffering real pain with this the last thing in the world you will want to do is exercise. And perhaps having sex could fall into the same category! There is mixed opinion regarding ejaculation. Sometimes it may help / sometimes it may cause pain. Drinking alcohol in my case is not a good idea. I know for a fact alcohol, particularly beer / ale will precipitate a flare up. John.
