Stephan couldn't even remember when it had begun.
At first, it had been a small matter.
One day, he discovered that sex had become painful as there was no precum. Even if his wife was wet, the penetration was painful for him.
However, this was easily solved by using a lubricant.
Then, as time went by, he found that he could not maintain his erection.
It was frustrating. He could get hard when his wife enticed him with their foreplay, but once she was placed on the bed … it just went flaccid.
He hid the truth from her well at first. He would quickly use his hands to get himself hard again before she realised something was amiss. Then, he found that it was getting harder and harder to maintain it and get it up again.
Once, it just never rose back up and he could not perform the deed. She didn't blame him in any way, and he brushed it aside as him being too tired and stressed out.
