I'm trying to see if I can find anything, but it would be interesting to see some statistics about the relationships between rapists and their victims.
I personally think that relationship - stranger versus someone trusted, might help to shed a light behind motivation.
Saying no means NO - if someone tries to go beyond this, they're going to have to physically be much stronger than me or make threats on my life. Taking away my ability to fight or remove myself from a situation I do not consent to is Power. The sex is just the consequence
And Mod Note - if such articles are available - it is helpful to link them in discussion if you have access
