Might be a long one but here goes...
Bit of background, husband and I have been together 16 years, married for 2.5 years, have 2 beautiful children together and we are saving for a house. We both have jobs we love and nobody else is involved.
So basically for the last 6 months or so he’s become more and more impotent. He struggles to get it up, then comes before it’s even had a chance to get hard. This used to be once in a while but now it’s nearly every time, and I find the whole soft thing repulsive if I’m honest which doesn’t do a lot. He seems to be incredibly selfish lately with just “sorting himself out” then wondering why I don’t really fancy it all the time. We have tried Viagra but that in itself takes any excitement or spontaneity out of the situation and then means if he’s taken it he doesn’t want to waste it even if we don’t fancy it!
We’ve previously had a very good sex life, but it seems to have taken a real nose dive over the last 6/7 months. He tells me that I need to “make more effort” when it comes to our sex life but honestly I find the whole thing hard work, any excitement in it for me is long gone and I definitely need to feel emotionally and mental engaged for me to even fancy it. The fact it can’t just happen any more is a huge turn off in itself, it feels like we have to book it in a diary 
Has anyone been through this? It’s making me desperately sad, he says if I don’t put more effort in then he will leave me (he won’t) I think he’s just lashing out about his own shortcomings (pardon the pun
)
Where do we go from here?
