Does a husband's addiction to masturbation and watching pornography affect his desire for his wife and make him not enjoy marital relations?

The relationship between masturbation and a decline in marital intimacy is not remote. However, it is not permissible to accuse the husband of masturbation or spy on him without clear evidence, for Allah Almighty says: "O you who have believed, avoid much [negative] assumption. Indeed, some assumption is sin. And do not spy."

The husband must safeguard his wife's chastity and treat her kindly. This is among her most obligatory rights, and he should not hurt her feelings. We advise the wife to counsel her husband, adorn herself for him, and supplicate to Allah.

A man's marriage to a second wife is permissible if he deals justly, but he is not allowed to threaten his wife with it.

It is not permissible to expose the grave nakedness except out of necessity.
