My wife and I have been married 2.5 years but together as a couple since college (11 years), and I'd pretty much agree with what eastbaydude said as far as frequency. It can vary a lot, but in a non-vacation week we're usually having sex 2-4 times.
It can definitely be hard to find time/energy on weekdays, since we both log long hours and our work shifts aren't always the same. Since one or both of us is usually beat by bedtime on a weeknight, I've found that one way to up the amount of midweek sex is to set the alarm for 30 minutes earlier than I really need (I view this trade-off as VERY worthwhile), so if the mood strikes on a weekday morning we can indulge it ... for instance, we did squeeze in a quickie this morning.
While we're not burning up the sheets as often as we were a few years ago, I think we do very well for a couple together as long as we have been. I keep myself very fit and I suspect that this helps keep us lustier than we might be otherwise.
