Hello
Welcome to HCM

You have problem of erectile dysfunction and probably also premature ejeculation. This is causing distress to you. Usual causes of erectile dysfunction are mainly psychological. But other causes as due to Hypertension, Diabetes, due to some blood vessels disease, due to medicines are also there.
I would advise you to please start doing relaxation exercises for immediate increase in confidence.

Medicines like Sildanefil, Tadalafil etc are very useful. Other medicines as yohimbin, fenugreek etc are also very useful. Herbal medicines like tantex forte is one of important drug in such symptoms.
Please visit your psychiatrist for these medicines.

Thanks

Hi,
As you say that normally you have proper erection of penis. So erectile dysfunction is ruled out
Another common problem is pre mature ejaculation. For you the watery discharge may be semen which can come without attaining erection. As you have normal erection without sex. So you are normally fit to do sexual intercourse.
First of all leave your worry - otherwise erection will be difficult. Don't try for intercourse - after a long travel, when you are tired, when you are in tension, when the circumstances are not suitable. Understand the sex. By a slow approach you will get erected. If she is not a call girl her satisfaction is more important than yours. There are so many technique to make her orgasm before starting the actual sex. Once you get erected divert your mind from sex in order to avoid quick emission. There are so many books regarding sex approach by a male. Understand and keep in your mind that you are 100% normal
Best wishes
