God made men. God don't make junk.
If you like coy or euphemistic language, you can say "the wedding tackle" or "the family jewels." They both imply a natural marriage-and-children connection to men's sexuality, which is right and just; and the latter is something I humorously said to my sons, when it seemed that were unwittingly vulnerable to getting smashed in the crotch with a hardball. "Ben, for God's sake, protect the Family Jewels!"
Get over yourself. Don’t preach about your personal language constraints. Family jewels is as much euphemism and slang as is junk. What men use as a reference regarding their nads, nards, balls, package, danglies, baby makers among others, is up to them. Believe me, we hold them in higher regard than any woman ever could.
I gave my sons the same admonition, as if they had to be told.
Lighten up.
