Two years into our marriage, my wife is preparing to give birth soon, but due to my age, I've been unable to fully satisfy her in bed. On the other hand, my career is going well, and I believe her devotion to me stems largely from my financial stability. I'm currently away on business trips frequently, leaving her to manage the household alone. Lately, she's been enjoying home parties with her new circle of friends—mostly younger, somewhat wild individuals. It might be an exciting, refreshing experience for her. However, I've been unable to reach her by phone repeatedly, which is starting to worry me.
