Well, you'vehit it right on the head.
I went through the same thing with my wife for quite a number of months.
Then after she agreed, so long as it was at her own pace. Then one night out at a local club she did something she has never done before in the fifteen years + we've been together.....she made a comment about the door bouncer.
Needless to say, I wasn't just shocked but got an instant woody, which I was almost unable to hide, sitting at a tall cocktail table.
I did't press the issue at all and just let it settle in. That night....talk about hot and heavy sex! It went on for over an hour.
To this day, periodically she grabs my hand and starts sucking the middle finger and goes absolutely balistic. flamethrow
