Re: Islam and marital rape...
Part of this requires one understand that there are situations in reality in which a husband FORCES his wife to have sex when she doesn't want to (take your clothes off now, bi***), and that this force is not at all similar to persuading a spouse to have sex (i.e. "oh comon!!! Let's do it!). The former is usually accompanied by violence and physical abuse and emotional abuse. The latter is just normal personal interactions with a spouse.
Again, its hard to conceive of it, but there are situations where a woman doesn't even want to be physical with her husband. A newly wed in an arranged marriage situation is just one example that comes to mind. I sure would be uncomfortable getting physical on the first night I meet the guy, and if he coerced me into anything ... how can that be "his right"?
Forcing someone to have sex with you - this is not something normal people do.
