Unfortunately there is very little anyone can do to "incite desire" in another person. Personally speaking I have been in a situation like that before. People should realize neglect of any kind increases an atmosphere where it won't take much for a stranger to come along who will put a smile on your face and in your heart.
The major difference between relationship/marriage love and those of (paternal, sibiling, and friendship love) is our romantic and sexual desire for our mates. I assume you have spoken to your man regarding your desire to increase your frequency. If not you should. Another thing you may try is to initiate things!
Those are the basic two things you can try. If those fail you are only left with 3 options. 1. Cheat (you probably love him too much for that) 2. Go without (you proabably love yourself too much for that) and 3.End the relationship and find someone who wants what you want.
At some point after all of the talk and not seeing any changes you will have to ask yourself, Is this a "deal breaker"? Only you can answer this question. The only person you can control is yourself. People change when they want to change.
Generally speaking there are only 2 reasons why your mate won't give you what you want. 1. They don't have it to give. 2. They don't feel you're worth the effort to give it to. When someone is "in love" they want their mates to be happy. Eventually you have to stop asking "Why he won't touch me?" and instead ask yourself "Why am I staying in a relationship with a man who won't touch me?"
Not long ago I wrote the following hub. I hope it helps you to put things in perspective. There are two groups of people. (Those who get what they want) and (Those who take what they can get).
Best of luck!
