There are many reasons I might want sex and it is neither always as good as sharing joy nor always as bad as using.
For instance, it is my preferred way to fall back to sleep when hit with insomnia. I will also find myself quite horny if I have no good books in the house and there is nothing worthwhile on TV. You'll notice in these two scenarios that it is mostly about me and a negative circumstance I find myself in, rather than being about my husband and wanting to share anything with him. Oh well, that's the breaks.
Sometimes it's intense and emotional and intimate, other times it's a quick O and back to dreamland.
I don't have addictive tendencies but I do have a propensity for "hobbies du jour" and get really interested in things for short periods of time. It remains to be seen whether my R is my latest hobby, or whether this will remain a long standing interest of mine. So far, it is one of the longest hobbies I've ever had.
