Sex in Everyday life

Our sex life is... nonexistent. We've had sex four times in the past year. I've made this clear a number of times that I'd like more intimacy. And the plea seems to go nowhere.

She says she's depressed. I can understand depression taking a bite out of your libido. I'm also losing interest in her, per se. This is not because of anything she's done, but because I lose interest easily and she's not interested herself.

I've thought about sleeping with someone else. It excites me -- more so the chase than the actual act of sex. I want to be desired, craved -- not too much, though, because I'll find that a turnoff, too. I'm very difficult to please.

I'm willing to settle on some issues because I want to have children and start a family, sooner rather than later. We can't get everything we want in a relationship, or in anything in life, for that matter. I would appreciate some attraction, some pull, though. Right now things are very comfortable, which is OK on many fronts, but there's something lacking in the sex department.
