Another man bashing thread. Everything isn't black and white, for goodness sake.
No, he should never call you frigid, however, a bit of context is everything. How long since you have had sex? A week? A month? A year? I could see how someone (man or woman) might snap if they feel constantly rejected. I'm female, with a higher sex drive than my DH, and I have certainly snapped at him when sex has been off the cards for too long.
Yes, he could, and should, deal with it better (as I should have done), but we're all human.
This thread would have you believe, that if you want sex once you're over 50, you're some kind of drooling sex pest monster. How sad. 50 is NOT OLD.
You've been told to rip his bollocks off, that he's a contemptuous wanker, that he's a sex pest, that you should tell him to fuck off, that you should become a single cat lady, that he's vile, that he's an absolute misogynistic twat of a man, that he's probably no great shag either, that you should be kicking him and his disappointing penis out the door, that he should subscribe to Only Fans, that he's coercive and rapey, that you should get separate rooms or better yet separate houses, that you've spent 32 years with a disgusting nasty pig, that he is a complete sex pest, that you should move to another bed room and tell him go to hell, and that you should tell him you no longer find him attractive in a sexual way and that your flaps have frozen over at the thought of it. Do you feel this way about him?
I think it's safe to say, that your audience are all older women who don't find sex enjoyable anymore. It's not a balanced view whatsoever. And I say that as a 53 year old woman, who finds this aversion to sex absolutely baffling. In your 70's, maybe, but in your 50's? Really?
Do you want to get better? Do you want sex with him, if you could solve your health issues? You've been with this man for 32 years, I am presuming you still love him? Patience is needed on both sides. Can you sit down and make a plan as to how to move forward that satisfies you both? You will look into improving your health, sex is only once a fortnight, and its not to be pushed outside of that. I can recommend Vitamin D, cod liver oil and collagen to ease the aching.
As I said, my DH and I are in our 50's. Sex isn't as frequent as I would like, but what we do have is lovely and keeps us connected.
Please don't write yourself off, you're only 57.
