I tend to agree with the "if it interferes with you doing what's needed to meet your obligations then it's an addiction and you need help" definition. I have yet to here of the "sex after work becomes the sex before work becomes the sex instead of work". Now I'm not saying you can't play hooky from work once in a while to have a romantic day with your spouse/s.o. just so long as it doesn't get you fired.
