"You tease me… I may not be a fit young buck able to wear out half a dozen women a night like your brother, but I’ve never given you cause for complaint in that area, have I?"
This was meant to show the insecurity of an older husband who is paranoid that his much younger, pretty wife will cheat on him, and also lives in the shadow of his playboy brother-in-law who is also his boss, but now I'm worried it implies something incestuous going on, lol
