There's also this https://biblehub.com/1_corinthians/7-4.htm Proverbs 5 is mostly talking about the ultimate consequences of intermixing with foreign women. When I read "wife of your youth" I am reminded of the villages of the past, where the local community would matchmake guys and girls of a similar age, when they were young, so they grew up with the intent of becoming married later on. Like childhood sweethearts. Where as foreign wives were more likely to be someone from another village, likely outside of your nation's lands, that you met later on in life. It's hard to know where to draw the line between hedonism and enjoying private time with your wife, but God did create sex as something to be enjoyed rather than abstained of and despised.
