what if you both agree to consent for your entire life before marriage?
I think this is starting to get into a self licking ice creamcone discussion....
Your initial question was:
if a woman is married to a man, and she isn't in a mood, should be allowed to in a last ditch effort, call the police, to get the upper hand on her husband?
The obvious answer is that is not an acceptable thing.
That does not mean you have the right to commit an act of violence through the form of forcing yourself on your wife when she does not want to.
This hypothetical is the sort of thing that you dont see in a healthy marriage.
Part of marriage is to celebrate your union through Christ and blessing you to have many children. It should mean that you're both wanting to have lots of sex ect... that's one of the blessings of marriage. It's not like it should take any coercion or physical pressure. If it does, you're doing something wrong or there may be a legitimate reason for hesitancy.
If there isnt and your old lady isnt in the mood and that is it, you should know how to get her there. If you don't you might need to figure out what you're doing wrong.
In my first marriage, which was not really grounded in Christ, I can say the only one or two times I ever went with out sex was when I was being a very poor husband and unloving and we were fighting, largely because of actions I had taken or failed to take.
I'm sure you also agree not to beat your wife before mairriage... doesnt mean its not still violence if you hit your wife. She might give cause to make you angry because you either chose wrong or dont know how to be a good leader in your own house. Doesnt mean you can just smack her for making you angry.
Making blanket black and white statements are sort of an argument from absolutism that don't really bear out in a Christ driven marriage.
