Wow, this is the first time someone married, on this forum, took upon themselves 90 days without any sexual pleasure at all. That's a huge challenge.
In SA they do this sometimes to "dry out"...
To quote the whitebook:
Healing in my marriage and in the family is one of the most blessed areas of this new life, even though things aren't always a bed of roses. I've found something better than lust—reality But I have to be willing to give up any thought of changing partners, either actually or in fantasy, even if it means not having sex at all. Each time, I have to surrender my right to sex and depend on the grace of God. What else can you call it? And there are times my wife and I have gone without sex for extended periods. But it's all right; sex is optional now. I have a choice. And mutually voluntary periods of abstinence for a year or so have proven to be the most constructive—and happy—times of our entire marriage. For me the key was finally giving up all expectation of either sex or affection, and working on myself and my defective relations with others.
It has been a totally new beginning for us. I'm just starting to get acquainted with my wife of seventeen years. I discover to my delight she's a person: unique, independent, an individual, a whole universe of personality I was blind to before. And the more I die to any thought of resorting to someone else and commit myself to this one union, the more pleasure and love and freedom I find.
I can't believe that the person I'm writing about today is the same one who used to think and do the things I've been describing. Actually, that other person was a slave; he was living in a world of fantasy and illusion, only for himself, and always alone. He had never matured through emotional adolescence and was spiritually dead. He could not cope either with his own emotions or with life in the big world out there, and was constantly running. Running to satisfy demands and lusts that could never be satisfied. Running from who he really was; running from others; running from life; running from God, the source of his life.
The running is over. I've found what I was really looking for.
