Re: Dying for a good sex life
If you know you are not ready then tell him not yet. If he trues to ignore your "not yet", end the session. Immediately. With prejudice. Inform him of the waiting period before he can initiate another session. If that "penalty time" exceeds how long he will be home, and thus means no sex until after his next 24 session at the hospital, that should educate him swiftly on the downside of ignoring "not yet". He is a doctor. He is capable of learning this.
When you can see it coming, duck!
