Unless you are a fish, a tetropod, an insect, or are an invertebrate then you don't have an intromittent organ, since those are the only animals to have them.

If you are a mammal, as I suspect you are, since you probably have fingers to type, you don't have an intromittent organ, you have a penis.

And no there is nothing you can do, short of surgery to increase the size of your penis.
