Good luck with that. Went through the same myself. Bottom line in dealing with my boy: Man enough to engage in that activity? Man enough to buy your own condoms, get a “big boy” bed, and your own place to use them. Also just two more words that opened his eyes real wide: “Child support.” Not coming out of my wallet, kid.
That’s what I told my wife last night. “So I’m providing the bed for him to boink her on. Should I buy his condoms, too?”
She laughed.
