At 47 years old should i expect to wake with an erection every morning?

Definitely not!: No man should expect to wake with an erection every morning! erections normally occur during rem sleep so if you happen to be in rem sleep when you wake up then you will have an erection. If you are not in rem sleep you will not wake with an erection. Rem sleep occurs during less than half of our sleep time so most men will wake with erections less than half the time.
