I’ve been married to my wife for 18 years now, for the last 5 l have been struggling with ED, I have been on Viagra, and now Cialis, sex in our marriage is good but not like it use to be, both have gotten older and jobs and kids. Talking with the urologist my health is good, he’s saying my ED is in my head, I can keep a erection when I’m masturbating, but can’t keep it during sex with my spouse, it’s like once we are together I feel like I’m not doing the job right and I start loosing it. I need to get past this stage.. please help.
