To the Married and Ain't Gettin It Crew, don't accept that shit, you can turn it around like I did. I just had a mature conversation, where I told her that I value her as a person and care for her on an emotional level, but that relationships also have a physical level that needs attention. Once you plant a seed in their mind that you're not happy, they start thinking...shit, he might stray...then they take it seriously.
As long as you're not in one of those relationships where your both always arguing, then you can reverse the staleness. I also made it a point to start romancing her a bit more, like the early days. She loved it and she's fully on board with it now. She initiates it more often than me now! WINNING!!!
