In the past few months, our sex life has been a bit dull, and every time I have sex with my girlfriend, it is like doing homework. So, I came up with a very exciting method.
At 10 pm, I called home.
"Dear, you go to sleep first, don't wait for me, I will be back a little later."
"Don't be too late, don't drink too much."
"Roger that, my dear wife."
