The country star admitted the couple are thinking about starting a family and - although they're not trying to get pregnant - they make love ''any time of the day.''
Speaking recently on 'Entertainment Tonight' LeAnn joked: ''Have you seen him? [Sex is] whatever time. Any time of the day. Whenever he wants it.''
The 30-year-old singer and Eddie, 39, will celebrate their wedding anniversary in April but their relationship began when they had an affair in 2009.
Eddie shares custody of his sons, nine-year-old Mason and Jake, five, and LeAnn admits they've discussed whether they want a child of their own.
She said: ''Yeah ... I think so. That's kind of the talk we've had for awhile now. Who knows? Not right now.''
In the same interview, the singer revealed she sometimes worried Eddie would stray after the way their relationship started, but feels their honesty will keep them faithful.
She admitted: ''I would be ignorant to say, and everyone else would think I am a liar if I didn't say yes, and I have at times. Speaking for him, I would actually say that's creeped into his mind.
''I think we've been very honest and open with that to each other and our conversations about it have only made me understand how much he actually cares, as much as I do, about being faithful to each other.''
