And you think your lover is demanding...
There's no getting around it, females are into foreplay; males not so much so. The considerate male must be willing to bend over backwards (it works for me) or suffer the consequences of a dissatisfied lover. Well, just be glad you're not a male Australian redback spider:
"It's long been known that the female redback who is roughly twice the size of her male counterpart, regularly eats a number of her male courtiers, although exactly what determines who gets eaten has been unclear.
"New Canadian research suggests that it depends on whether the female has been satisfied by the duration of the stimulatory courtship, which entails the male vibrating the female's web for approximately 100 minutes."
The batteries fail and you're dead.
