Hello and welcome to healthcare forum.
Size of the penis is proportional to the body habitus of a male, so you should not get worried regarding yours.
There is no medication or surgical procedure available to increase size of penis.
And for your information only anterior 4 cm of vagina is sensitive.
So, have healthy diet and regular exercise build up your confidence.
