The Matrix Reloaded simple question?

I believe they've had sex on the Nebuchadnezzar, but probably very quick & restrained. After all, they are on active military duty on the ship. They can't be distracted. Also, they've been doing all these missions and away from Zion for so long. Think of it as the soldier who comes home on leave after being overseas. The first thing they're going to do with their significant other is, hot, wild, passionate, no holds barred sex.
