As long as I want to.

Historically its been a struggle for me to get off at all. But there was a change recently, and now I'm able to get off but I have to be in a good mental spot for it.

I have to brag about yesterday, where my wife brought me to orgasm in the morning before she went to church, and again that evening before we went to sleep. For someone who has had trouble climaxing before, and is now in his 40s, it was a shock.
