Sir I am going to get married next year in January. I feel I am suffering from low libido and erectile dysfunction since I don't feel that excited. I had been three times in sexual relation and all the times I failed almost in sustaining erection. One time phone rang in between, once due to pain of partner and I feel my partner has vaginismus (assuming) as she contracts her vagina a lot and in this I lose my erection. I want to have a stronger erection. I masturbated a lot and now I usually engage with my partner on phone otherwise I have decreased my masturbation frequency. I love her and don't want to disappoint her. I feel I had been addicted to porn and due to this I have got lack of interest and now my threshold has increased. I want to know can I take L Arginine or L citrulline! Please help me.
