Actually, morning wood is caused by REM sleep, where there is increased blood flow to the genitals for both men and women. Check your woman for engorged labia.
In the morning, we have more REM sleep periods than we do at the start of our sleep cycle, so we're more likely to wake up with a woodie in the morning than we are earlier in the night.
