Hi,
Welcome back to icliniq.com.
I have gone through the provided answers and completely convinced that the pathology lies with psychological aspect and there is nothing which can be called organic problem or real muscle weakness. Below here I am delineating few of the strategies which will help you in the erection problem. Firstly get rid of thoughts that you may be sexually inadequate or your doubts that you may not be able to perform properly. This is because performance anxiety, feelings of sexual inadequacy, self-doubts, guilt, past negative sexual experiences, poor communication or understanding with the partner, etc., can all affect sexual functioning and performance. Removing such ideas will eliminate the majority of causes for your poor sexual performance. Removing the doubts and fears, and improving your self-confidence levels will definitely help in improving sexual performance.
Remember that sex is not just a physical act but also a psychological process involving an expression of emotions, intimacy and love. So, just involve yourself in those feelings and stop focusing on your "performance" alone. Once you do that, then I assure you that your sexual performance will automatically improve.
Most importantly, performance anxiety soon becomes a "vicious cycle" That is, anxiety leads to poor performance and poor performance then leads to further anxiety and this keeps on increasing. In my view this vicious cycle already established in your case and there is definite need to break it altogether and take control of yourself.
One more problem responsible for psychogenic ED is inadequate sexual arousal. When the person is not properly aroused, the blood flow to the penis is not maximal, and so, after a few strokes, the erection weakens and ejaculation occurs. The way to tackle this is not to rush into intercourse quickly, but wait till you get fully aroused. So, increase and spice-up your foreplay. Make sure that you initiate penetration only after both of you are fully turned on. Good foreplay not only arouses you but also sparks off the mood in your partner. So, when your partner is also aroused and involved, then things keep flowing smoothly and effortlessly, and you do not have to be constantly anxious if you are satisfying your partner or not.
Distract yourself stop "monitoring" your sexual performance. Try putting on some romantic music or mild lighting while you make love. Think about the things that turn you on. Taking your mind off of your sexual performance can remove the worries that are stopping you from getting fully aroused. Wish you all the best in your sexual health.
