Implied consent cases are always the most difficult to determine.
Partners can do all sorts of things in the heat of the moment which generally do not occur in regular life with people one does not know. That includes good things and bad things.
However, rape that occurs in marriage or an on-going relationship is
not typically an "out of the blue" behavior. In properly documented cases, it turns out to be a continuation or persistence of abusive, controlling behavior by whomever is doing it (I think there are plenty of women that return the favor as well, but not in the conventional sense).
I also find it a bit odd that some people think a guy cannot expect free access to his wife's body for whatever he wants....
Hmmmm.....human versus money, yeah I see the confusion
It is simply a case of you have free access as long as she/he is a willing participant (role playing aside). Come on holmes you don't have to give her acces to your damn bank account. If you think that's
all she's interested in then evaluate your choice and cut him/her off.
