No Straight Jacket... yet

So after a yesterday's melt down, i am feeling much better today and not quite so paranoid as yesterday. It's been a pretty uneventful day, just the usual stuff, cleaning, laundry, nothing exciting. Last night i was to fuck my husband but had a "child-interuptus"...lol Will try again tonight see what happens.
Basically, i am having to try to not look at it as a chore, i had at one point gotten past that and was not bothered by fucking him and sometimes actually looked forward to it. But for the last while, it seems no matter what i do, my husband just can not cum without stroking himself off. And to be quite honest, it really really annoys me. While i don't really care if he is attracted to me, i can't help but think its something wrong with me, am i not tight enough,  am i not sexual enough for him, what is it??
Well, my Master and i have talked about it quite a bit and really it boils down to it being his problem not mine. There is nothing wrong with me, i am certainly tight enough..lol having pulled off several condoms as well as pushing cocks out of me. It's not that i'm not sexual, i am, i mean i know there are those out there that would fuck me in an instant if they could, as well as those that have expressed the want to fuck me if ever given the chance.
The only thing i can think, honestly is that he masturbates too much. i know he spends hours looking at porn on the internet and i'm sure he strokes to it often as well, i don't really care. But, when you have a live, hot, dripping cunt to fuck, would you not rather that than your hand??? 
What my Master has come up with lately is that i use him, take my pleasure from him and then either i stroke him to orgasm or he can do it himself. Now you may be thinking, why not a blow job, well the answer is this. For a really really long time, that is all he wanted, and because i was being the good wife, i would oblige. And so for well over a year, that is all our sex life really consisted of, yes he'd fuck me occasionally, but for the most part, it was either just a blow job, or i'd give him one before he'd fuck me, and i really hate it now. Not that i hate blow jobs, pffttt don't be silly, i just hate giving him one.
Anyways, we shall see how tonight goes, i could use a fuck, although a really good one and i know i won't get that from him....lol but i suppose he'll do in a pinch.
