Tom, In an HD guy I suspect you'd be right. An LD guy would have a much harder time recovering from rejection.
You might find it helpful to think of your LD wife when thinking about the LD husbands here. For instance, if your wife came to you and initiated and you had just mbated so you had to turn her down, how would she react? Leaving aside hormones and all that, she would most likely be devastated and hurt and resentful.
Now, before you say it, yes I KNOW that this scenario would never happen b/c you would probably be either dead from shock or you would recover just fine and give her the ride of her life, but it is an analogy!!
If I reject him he will not approach me the next night. It seems to kinda kill whatever desire he had going for me. (which I am guessing would be the case for your LD wife..whatever desire she may have been acting on would have been eradicated by a single rejection)
Oh and one more thing: My h's desire increases for a few days, culminating in a horny period after about a week of no sex, then after that it goes drastically down and to the point where it might be a month or longer before he even thinks of it.
