Whenever they feel that their marriage has reached an all time low or is in severe danger of doing so, many martial partners will raise the question: "can I save my marriage?" The answer is both yes and no, because if the relationship is not working out (for whatever reason) and only one spouse is making all of the effort, then the relationship will not get terribly far. A marriage has to be a relationship which prizes honesty, commitment, loyalty and trust between both spouses and where both spouses are made to feel valued and appreciated. An unequal partnership is an unhealthy relationship and whilst it may function for a while in the short-term it will eventually falter and then die a death in the long term.
However that said, it maybe that one of the spouses has to take that all essential first step towards making progress and so they may want to try and initiate the new regime of change. The same problems and issues plague marriages across the world and irrespective of length, or culture and thankfully the solutions are equally universal.
If you feel that sex is the issue (whether this is due to the lack of it or the "quality" of it) then focus on this. It is important that the spouses appreciate that males and females regard sexuality in different ways and there will be different aspects of it that they will value over the others. Men for example, tend to be rather visual creatures who prefer overt and prominent displays of sexuality and femininity. Ladies, why not surprise (and treat!) your husband to some new lingerie? Bring him his dinner in it, and watch his eyes pop out of his head in a heady combination of lust, desire, surprise and delight!
Nothing excites a man quite so much than fellatio (oral sex) and again the principle of conspicuousness outlined in the above paragraph is equally applicable. Make sure you wear a very bright lipstick be it red or pink to accentuate your mouth, groan and moan whilst performing it and make sure to compliment him on his size/taste/whatever.
As pleasant as fellatio is and can be, one of the surest ways to excite your man is to make eye contact with him during it. There is nothing quite so delicious or erotic in this world than to have a female adoring your penis with a look of submission and devotion in her eyes.
