I can take Crazed's point as long as we are talking about non-alcoholic, non-abusive relationships. Once addiction has colored the relationship, as we all know, we're operating under coercive conditions. Frankly, it's a mindfu** and sex plus addiction is usually weird, disappointing, and stunted because we're sleeping with people who by definition can't do intimacy while using.
On the other hand, I really don't cotton to telling survivors how they ought to feel. This is the survivor experience, and it's really not up for debate.
