(The following is a personal post from one of our group members.)
Since "the only requirement for membership [in SA] is a desire to stop lusting and become sexually sober", it must be something very important for me (and anyone else who wants to join SA). But the importance and the actual meaning of those words was not something I honestly accepted when I showed up at my first SA meeting in 1989. My desire was not to "stop lusting". My desire was to get control over my acting out behavior. I erroneously believed that sexual acting out behavior was my real problem, and if I could get control over that, I would have succeeded in my purpose for showing up at meetings.
And at first, I started to "succeed". I'd only act out each week the day after the SA meeting just so that I could say that I had some "sobriety" the next time I showed up at the meeting, (Yes, pride is one of my character defects.) Eventually I started to string together longer periods of "sexual sobriety", and even achieved a year of sobriety at one point before crashing and burning and relapsing as a consistent pattern. I stopped any regular attendance at SA meetings and the progressive nature of my addctn took its natural course. I became a "true addct", I had completely "lost control" instead of achieving my purpose of gaining control.
But wanting to be "in control" is precisely the opposite of "surrender". And surrender is what I needed, even if I didn't want it. What I truly needed was to have God in control of my life, a Power greater than me and greater than lust, One who "could and would" restore me to sanity and keep me sober and free of lust's bondage. I needed a right relationship with God, but that had to come on his terms, which is why he is God and I am "not God".
For me to really "desire to stop lusting", I had to be beaten thoroughly, to lose the fight, to "give up, let go, and let God." I had to become thoroughly sick and tired of myself and to finally acknowledge that the problem was me, the problem was in my heart, not in my behavior. I needed a change of heart, and God was willing to do that when I surrendered to him. And when I had finally lost the fight and began to experience an attitude of surrender, I became willing to work all 12 Steps as directed by a sponsor. And that led to a "spiritual awakening" and a "happy and joyous freedom" I could otherwise never know.
