I’m 75. Work with trainer for fitness. Take TriMix for ED. I suffered weak erections which lead me to research and pumping. Only 2 weeks in but wow! Full hard turgid erection for 20-30 minutes. Love it. I fear I’m pumping too hard. Typically, I’m thinking if 2 weeks gets me this, why not more? For now very pleased. Used an electric 2.5 cylinder from Amazon. Would value experienced advice on stretching. Not sure if that’s practical.
