No worse than I am for having the quantity most people crave, but wishing for quality. And flirting online for similar reasons (although, since I'm married and have a handful of morals left, won't physically be cheating).
How would your husband feel about some form of consensual non-monogamy (polyamory, open-marriage, etc)? This way you can find a way to get your physical (and possibly emotional) needs met.
