temptedmum: all yours posts could have been written by me.
DH and I have been struggling with this for the last 10 years. Unlike you, we have tried everything - counselling, therapy (individually and together), doctors, consultants, viagra, various other drugs, legal and illegal - but things are still the same. DH's sex drive is non-existent and he also suffers from impotence. We have conceived our children through a lot of viagra and a lot of tears (his).
Outwarded we are the perfect family - middle-class, good jobs, he is successful and 'powerful' and good looking.
Every year I think "Maybe next year will be different" but nothing is changing. He finds it incredibly hard to talk about it. He finds each failed 'attempt' devastating. He is very depressed about it but also very fucked-up inside. I have wondered if he is gay too - but he says he simply doesn't have much desire at all and when he does, his body doesn't act on it.
I use sex toys all the time - nearly every day - but it doesn't help. I want to have him. I love him so much. I find myself using sex toys and thinking about him and somehow that's so awful it breaks my heart.
I can't discuss this with friends and it is so hard for people to understand. My friends are always moaning about how their partners bother them for sex and I am so envious. I can't look at couples we know without feeling jealous.
Sometimes I am so full of rage I could happily gun down random strangers in the street (if I was American of course). :)
I don't know if I can spend the rest of my life like this. I love him so much but all this stuff never leaves my mind.
So I don't have any advice, but you aren't alone in feeling the way you do - even if it feels like you are.
