My husband does this "Oh you are aware that J got it 4 times this week, i'm only at 3"
I always reply "Did you enjoy them? Are you happy with our sex life?"
Both answers are always "Yes"
So then I tell him not to worry about what J gets as long as he is satisfied as well
Wife to D (36)
Girlfriend to J (27)
Open for 5 years Sharing my D with C almost the whole time <3
