Welcome to the SI101 Board and its Forums. I hope you enjoy participating. Please begin by reading the SI101 Forums section as well as the Index located at the top of the main screen.
Here is an article that should help the anxiety you have about your penis:
For Boys Only- A Matter of Size (Regarding your penis)
There are no potions, pills, pumps, or rings, that will increase the overall size of a penis on a permanent basis. Pumps are dangerous because they can and sometimes do rupture vessels.
> I was wondering if they actually do what they are meant to do.
Yes, however, what is it that they are meant to do? As advertised or as a result of the advertising? Answer: the latter. They make the manufacturers and vendors rich. So, in the words of our California Governor - "forgetaboutit".
Lastly, please read the article half a dozen times until the message sinks in. It is not the size of your penis that matters, rather, learning how to become a great lover using your mind, and then your hands and body. Learn what turns a woman on, learn how to turn a woman on, these are vastly different than what turns guys on.
If your desire is to be a world class lover some day, get started by reading all the other articles listed in the Index.
