Men, take note.

Both Viagra and Cialis should be taken no earlier than an hour before the intended sex. If you recently had a hearty lunch, throw in another forty minutes (about the same time it takes three slow dances with breaks to drink lemonade. Or the recitation of the poem "Romeo and Juliet". Or a joke told two hundred and fifty times in a row. In general, you have to figure out how to kill more elegantly time).
