I think psychologically it’s much more complex than someone else has explained on here. I’m very attracted to my girlfriend, she is amazing. I can get an erection fine with her but the moment I worry “what if I lose my erection” it goes and my head over thinks and I’m never going to get it back if I don’t get out of my head. Mindfulness helps reduce anxiety, being in a communicative relationship will help, mostly it’s tackling the issue and the worry that is causing my ED. Once I am more aware of why it happens then I can be more aware to prevent it. The blood tests are to rule out physical as I have another condition that can potentially effect my hormones, so my issue is either part physical part psychological, or fully psychological.
