Unmarried people primarily struggle with it.
While there is indeed much adultry, married people for the most part are satisfied with chaste sex.

As Hebrews 13:4 points out, the marriage bed is undefiled.

[Resettozero]

In the context that your usage of the word chaste in relation to one who is married means undefiled by adultery, I can agree.
