My marriage and ED

Hey, I know there are probably a million and one similar topics.

I've been married to the loveliest man in the world for two years, and his ED started pretty much around the time we got married. Since then I've done my best to be understanding and not put any pressure on him, but after two years it's getting more and more difficult. I feel so weary of it. Our sex life has dwindled to the once or twice a week he takes a Viagra or Kamagra tablet, and it's perfunctory to say the least. Outwith this time, he shows almost no interest in me sexually, and the ultimate effect of that is, it feels awkward and unnatural when he takes a tablet, like it's forced. There is no natural sexual intimacy in our relationship and frankly, it's like talking to a brick wall when I raise the issue.

I feel so angry that he shows no interest in me and recently I've become angry at the fact that he didn't have ED before he met me. I feel angry that with previous partners he had a fulfilling sexual relationship, yet here I am two years into a marriage and he has no interest in a fulfilling sexual relationship with me. I feel almost like I've been cheated, and sometimes it's more like utter rage than just mere anger. I do love him and want our marriage to work but I feel like if I try to raise it or talk about it too often it puts pressure on him. I feel like I'm doomed to an almost sexless marriage, and worse, a marriage devoid of intimacy. The fact that it feels so awkward when he uses the tablets has in turn put me off sex and my sex drive itself has nosedived completely.

To be honest, I just don't know where to turn or where to start and I confess I have considered leaving him, which would really hurt him to know.

Any advice would be much appreciated.
