Faithled,
My husband began experiencing ED several years ago, at least that's what he thought. In reality, I thought he was great, but he CLAIMS it was because he hid his Viagra prescription from me. I don't know which came first here, the chicken or the egg, because when Viagra was first introduced, EVERY man got some of those little blue pills just to see if it would make them more virile (to put it nicely!).
Anyway, my husband did begin experiencing some ED, although it was more of a problem for him than me as I have experienced my own issues with aging... it ain't fun and I took it in stride. Again, which came first, the Depression or the ED?? Good question... and if you are a man whose very identity as a MAN is wrapped up in his ability to perform like a porn star, wouldn't an affair with a younger, new partner that proves you've "still got it" be tempting?
In my husband's case, he felt so down and depressed and OLD from, well, mid-life that the first affair-down that solicited him got his attention in a big way. He has admitted that "she told me that she was just extremely attracted to me". So, imagine that the "newness" of a partner adds a little lead to your pencil at first, how easy was it to get entangled in the trap of their own making?
I recently posted my Fantasy of the Day: Hide his Cialis prescription so OW can see what sex with a depressed, 46 year old man with ED is really like!!LOL!!
