Hi. For last 6-7 years, I had problem where a slight sexual arousal or any intimate chat or scene in TV or mobile would make me nervous, heart beat would increase and make me ejaculates. I tried homeopathic medicine for no success. Later I consulted 5 months back to a psychiatrist who found I was having depression and anxiety. And after taking his medicine from last 5 months. My nervousness and heart palpitations with sexual activity has vanished. But now after being sexually aroused or when I watch any intimate scene. I can't hold my erection for long. Time. I need treatment for this. And wanna know the cause. And yes. I have excess skin on penis head. Which doesn't move back, when I have erection. What to do of it? Need permanent solutions.
