No it has no effect on the penis at all.
When your girlfriend tells you "You have a weak penis" or "Your penis is weak"
Since masturbation does not cause weakness, you may have some other medical problem causing you feel weak. You should see a doctor for proper medical evaluation.
The gel-like substance you are experiencing after masturbation is likely pre-ejaculate, which can sometimes be mistaken for semen. It is normal for this fluid to be present during sexual arousal. Feeling weak after ejaculation can be a normal response to the release of hormones and the exertion of energy during the act. If you continue to feel weak or have concerns, consider speaking with a healthcare provider.
mastrubation
a dick/penis
No it does not.
Just Stop.
I assume you mean interfere or cause some sort of problem with growth. It will not hurt a thing. Male or female, there is nothing wrong with masturbating and pretty much everyone does it.
It means penis
Stress relief
No, there is no direct correlation between a person's physical strength and the size of their penis. Penis size is determined by various factors, including genetics and hormonal influences, and is not related to a person's physical strength or weakness.
Masturbation doesn't do any damage.
