It's Official Welcome To A Sexless Marriage

Two nights ago I couldn't get it up when it counts. I'm 60 in January, I'm on multiple meds for blood pressure, blood thinners and gout. I feel like a failure because I couldn't get hard enough. The last time we were together was over a month ago and I came too fast.... couldn't last one minute. I don't feel less than a man, but it's seems I'm no longer her lover just a good friend in love with my wife who is now my roommate. This is my official welcome to a sexless marriage. A part of me has died. I left the silicone lube in the hotel room because I won't needed it anymore. Kissing and cuddling is all that remains. She even tried to masturbate me but it stayed soft. I've only experienced this once in our marriage. Almost 40 years...
