Hi,
Thanks for posting in HCM.
I have read your description and understand your concern.
What problems you are is facing with reference to shrinkage of penis and weak erections is more of psychological problem than physical. Most men during your age and when they start to indulge in sexual activities find such problems and it can be overcome over a period of time.
Masturbation is a healthy normal physiological phenomenon and it does not cause such harm. Hence make sure that this is not a mistake you have committed.
Bending of penis towards one side is normal as about 70% of men has penis which is slightly deviated to the left or right.
To overcome
erectile dysfunction, you can use Tablet.
Tadalafil 30 minutes before the act to achieve good erection. Horny goat weed, which is a herb can also used to arouse sexual desire and for erectile dysfunction.
Along with this, you need to practice behavioral technique like '
pause and squeeze' technique.
Slowly, over a period of time, you would gain confidence and can overcome the problem and can limit the usage of medications.
You can also practice
meditation to keep your mind calm and spend more time during foreplay to increase your confidence.
Hope the information provided would be helpful.
All the best.
