I know many women who would disagree.
But giving without expectation of receiving is also the key. Unconditional. Period. That is in the bedroom and out. If everyone expected to received a gift on Christmas for everyone they've given, imagine what a selfish world this would be. You do things sometimes, just because.
It has to go both ways, or it doesn't work. Maybe that's the case with those women.
It takes communication, friendship, and respect.........and it doesn't happen that often, unfortunately.
Of course, a key element, IMO, is a God-centered relationship. HE'S the One who created us, and designed marriage for our mutual benefit, AND pleasure. When two people are off course spiritually, lots of other things go wrong in a marriage, including the physical.
That was really a sad article.
