Thanks for choosing health care magic for posting your query.
I have gone through your question in detail.
Please try to understand that masturbation
is safe and will not lead to change in the size of the penis.
There are no medications to increase the penis size or thickness.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.

Wish you good health,
