I’m 18 years old, 5 feet 9 inches tall, and I weigh 155 pounds. I would say my penis is average, but I wish it was a little bigger. It is about 3.5 inches long and 4.5 inches around in its flaccid state. When it is fully erect it is about 6 inches long and 5.5 inches around. Sometimes I feel that my penis will not fully satisfy a woman.
Fully erect, well retracted foreskin. Good proportions.

Same penis next to measurement tape. 6 solid inches.
6 inches is the perfect average. This said – you are good to go. It’s not too small, not either big. It’s the perfect average. However, your perfect size would be around 6.75 inches in length and around 6 inches in girth. This can be achieved in 3-4 months using a penis pump.
