It sounds like your therapist isn't quite getting the message...

Sure, most of us are heavily triggered by sexuality...that part is normal. But it seems to have an abnormal hold on you. One orgasm is enough release for most people! It sounds like your "off switch" is broken...

I don't blame you for hating to hear sex talk...it must be like someone poking at a wound.

Sometimes "sex addiction" is used as a moralizing term. Try not to look at it that way...you aren't a bad person for having this problem.

Have you seen a psychiatrist (MD) about this? I am NOT any kind of expert on this stuff, but it sounds like a medical (PHYSICAL) problem to me.

Do you have any other psychiatric symptoms? Hypersexuality can be a very distressing effect of bipolar mania. (Maybe this is not you at all...just asking.)
