Welcome to HCM
We understand your concerns
I went through your descriptions. I suggest you not to worry much. Ejaculation on talking to a girl is not actual ejaculation. It is just lubrication. It happens to every man. Nothing to worry.
Night fall happens because body want to eject the excess sperm. You are very romantic and sensual. Your body produces excess sperm and body want to release it. Body finds the easy path and that is night fall. again nothing to worry.
Size of penis is not at all a matter of concern. Even a 2 inch penis (erect) can satisfy a woman and you definitely have it. Again nothing to worry.
I can assure you that these conditions are not at all harmful to your marital life. You will enjoy it. All these are unnecessary thoughts. The pain is not actually there. You are anxious and therefore the pain is in thoughts.
