I'm only saying that you ascribe certain properties to the populations you are dealing with. And there are definitely places in the world where your assumptions fail to hold up. But biology ALWAYS holds up.
By the way... I was being kind. Rape is only ONE whole in your plan. There are many. For instance, your plan also assumes women will never simply get horny. Or that they will only "get off" in certain predetermined ways that your plan deems acceptable. Your plan assumes a lot ... and all of it from your own perspective and belief system. If we work within biological limits... we achieve our goals regardless of the local belief system.
This is the point I'm making... you are asking that human females satisfy themselves with that which YOU deem it acceptable to provide them. What happens if a human female, indeed many human females, decide they want something different???
