Can a "good guy" inspire wild, unbridled passion?

I struck up a conversation with a girlfriend once about the movie "9-1/2 Weeks", and discovered I had struck a nerve.  She loved that movie, and always wanted to find a man who made her feel the way Mickey Rourke made Kim Basinger feel in that movie.

And in later conversations, she mentioned that in her "younger days" she had been impulsive and "wild", at times inspired by scenes in that movie.  She had had sex in a stairwell, on a car hood, on back roads, under the stars, in the ocean, etc. with various guys over the years.

I was really close to that woman, and we had even considered marrying one another.  But I was struck with the contrast between the intimate side I knew of her and the side that she had shared with other guys who meant much less to her.  She had a wild and reckless and impulsive side of her I wanted to know!! And I have always craved to be the object of that sort of desire!! 

But I could not draw that side out of her.  What she shared with me, she assured me, was deeper, more meaningful, more intimate.  I was the man she adored, the one who's gaze and touch reassured her, with whom she felt most intimate and cared for.  At the time, I was the man she wanted to be with the rest of her life.

I am, and fear I always will be, a decent and caring guy.  I'm the sort of guy a woman wants to keep in her life, and talk to and share secrets and be intimate with.  But as far as I can tell, I'm not the sort women want to go wild with outside of bed.  Despite my efforts, I draw out the "proper" side of women, the side that waits until we're home and the bedroom door is locked.

Even though I have been close with that one woman who craved wild loving too (at least she craved it with other guys), I have not been the object of anyone's unbridled, wild, impulsive passion.  I have suggested other safe places (my locked office, the locked roof of a building, alone in the mountains or desert) but find my impulses and affections are always steered back to the safety and comfort of bed.  Once there, they are comfortable enough to let their hair down....  But why can other guys inspire that reaction outside the comfort zone and I have to wait until it's safe?

My question to you is this: is it possible for a "good guy" to bring out the wild, unbridled lustful side of a woman outside the bedroom?  Have I just not found "the right woman" yet, or does it require a "bad boy" to draw out the "bad girl" in a woman?

For the ladies out there, tell it straight - have you shared your wildest sexual impulses with a good guy in your life?  Or should "good guys" the world over just accept that their sex appeal is the reliable, safe, familiar variety that ladies find only in the confines of the bedroom?
