I am sure the financial situation also influenced his mood and mental state. When it comes to men’s sexuality, there is a myth that they are always sexual, despite what they are currently dealing with in their lives.
The truth is that one of the most common reasons a man’s sexual desire is affected is due to financial issues. It can significantly affect their masculinity. When men fail in business, it can impact their ability to believe in themselves, inhibit functionality, and lower their sex drive.
I would recommend a psychologist unless it is only his sexual desire which is harmed and not his mental state, in which case I would recommend contacting a sexologist. He or she can help him identify what influenced his sexual desire and how to deal with it.
