Yeah i think youll have to try finding the source of your issue and work from there. Ive had that issue more than I like to admit but its only been with indys which leads me to believe it's all mental. For me, it's the anxiety before meeting the chick and then being expected to get erect within a minute of the meeting. It doesnt help that i have an old lady at home. Its all a bit nerve-wracking for my sober mind. Once the nerves kick in, i start getting in my head. I may work up a serviceable erection but ill last a few mins tops. AMPs work great because theres some sensual aspect, some build-up, etc that gets me going. There's typically never any clock-watching or shitty attitudes. They put in effort to get you aroused. Id imagine if I was under the influence of something that may alleviate my symptoms but that would be too much prep work.
