Husband moody the whole time.

He sounds rather selfish to me. Can’t he he just be satisfied with a ‘J Arthur’?
I couldn’t bare to be with someone like him.

Once every two weeks isn’t going to satisfy a man who still has a powerful drive but forcing you to have sex against your will - well there’s a word for that.

If sex is giving you joint and limb pain then you have right to say no or find some other way to do it. Sex doesn’t have to be penetrative or involve the man pounding away or any kind of gymnastics.

I was about to say the same as Lathyrus. Would it bother you if he went elsewhere to satisfy his needs? If the answer is no, then point Percy in the direction of Tinder or similar. Plenty of women there are looking for casual hookups.

Obviously you don’t enjoy it at all. He’s not very good at it, is he?

Probably a bit late to tell him to make changes though.

Would you object if he went elsewhere for sex or would you be ok if it improved his mood either way you?

Reading your post makes me so glad I left my first husband. He was exactly the same , our lives revolved around his desire for sex. Sadly I don't think your husband will change , my ex husband, ( now 64 ) has gone through another wife and several partners since we split. According to our daughter , he's still the same now !! . You may need to leave him for your own health and well being

An hour of sex at his age would suggest he's possibly taking a Viagra type thing,my husband used them for a while till I said no more.Men never seem to understand that women aren't always ready , especially as we get older,let him sulk ,however there is also the thought that they think they're less of a man if they don't keep you happy..talk to him,put your side across

Completely unacceptable, my sympathies. However you need to actually think about what you have written here and how you would advise your sister, mother, daughter, friend in these circumstances.

Sorry OP he sounds like a nightmare. Treading on eggshells round someone would drain me of the will to live.
And he CAN control himself, he just chooses not to. As for an hour of sex, that’s insane and best left to those in the heady throes of young love/lust.
Have you thought of leaving him? Seriously, what are you getting out of it?

Oh Ginpin, that does not sound like a happy marriage to me. You have my sympathy. Sadly, I expect that he is unlikely to change now.
I am glad, reading such posts, to be living alone.

Well, I beg your pardon but he CAN help himself ... he simply chooses not to.
