A man and a woman, 41 years old. We've been living together for a year. and 4 m. We have sex two to three times a week. As the duration of the act, the first time from 20 to 25 min. repeat between 30 to 40 min. I hold on before I'm done. The problem, my wife's excitement before it's over, I'm always done before she does. This happens at the first and second times although my sensitivity is decreased. I've found a solution to end it with my hand, and yet after I continue I can't hold back for a long time. I've never met a woman like this before. I guess I'm going to have to improve :) I'd be interested to hear opinions.
