good god CG are you still posting here?
Right, well, considering you have seen fit to judge the op, second-guess what she should be thinking, and what her dh should be thinking, and have basically dismissed everything she feels and fears and has had the courage to post here, here's what I think.
I think you read this op and it struck a chord with you.
You looked at the words of the op and what they said, and suddenly you realized that this is your relationship.
And as you realized this you realized that you've never had an issue with it, never thought to have an issue with it, because to you this is normal - not only the concept of your husband beginning to have sex with you while you're asleep, but him continuing to do so even if you wake up.
And it can't be rape - how could it? After all, you both love each other, and he wouldn't do that to you, so it's not rape. Except he does it to you, and it's never occurred to you to mind, or object, or question that it might be wrong. How could it be wrong - he is your husband...
But you know it's wrong, don't you? You can't admit that it's wrong though because you've accepted this state of play in your own relationship, and rather than accept that this is how it is in your own relationship, you have to fight against the assumption that the op is right, and those that don't agree with her are wrong.
If you genuinely believed you were right you wouldn't still be on this thread protesting just how right you are - you would have read it and moved on because it didn't apply to you.
But instead you feel you need to stay on this thread in order to convince everyone else that it's not like that.
But it's not everyone else you're trying to convince, it's yourself.
Think about it.
