We are late 40s, married 25 years, grown up DC. Over the years DH sex drive has dwindled, and we are down to once a month at most. I'm no nymphomaniac, but this is just not enough for me, and I'm getting really down about it. He used to have a porn habit when he worked away a lot, but he's worked from home for a few years now (as do I) so I doubt whether that is the issue now. He was honest about it then so I have no reason to doubt him now when he says he just has no desire and would rather read a book. He seems content to accept that it's an age thing (however I know plenty of people our age with regular happy sex lives) but I just can't go on like this. He has had intermittent problems with ED, which seemed to be made worse if I made the first move (maybe he felt under pressure) so consequently I've left the decision to up to him whether we make love or not. This means that we hardly ever do. In other ways we are compatible, we have common interests and enjoy each other's company, are good friends etc. I just have no idea how to move forward without putting pressure on him and potentially making things worse. I've tried wearing lingerie which always used to get him interested, but the last time I did that he couldn't perform and I was left feeling like a sad desperate old woman, so that's been confined to the back of the wardrobe. He has said before that the stress of work affects him, but he's had more stressful jobs than this before that didn't affect our sex life. I just don't know what to do.
