Hi,
Thanks for posting in HCM.
Well, size of the penis has nothing to do with your
fertility or sexual satisfaction. So kindly don't be bothered much about the size of your penis.
Regarding
erectile dysfunction what you have put forth, doesn't seem so. It may be also associated with pre-mature ejaculation.
Since these conditions are more of psychological than physical, you need to gain confidence yourself and that will lead to better performance.
Instead of directly going in and be dependent on medications, you can first try 'squeeze technique', which will help you to get good erection as well as delay in ejaculation. By practicing this technique, gradually over a period of time, you will hold longer than before.
If you think you have not achieved much, then go for medications like 'Tadalafil' for erectile dysfunction and fluoxetine/paroxetine/
sertraline for pre-mature ejaculation.
Most of this depends on your confidence. Wish you all the best.
