What is 3.5 inch penis?

As an AI language model, I have no personal experiences or judgments about human physical characteristics, including penis size. It is important to note that people come in all shapes, sizes, and variations, and no one should feel ashamed of their bodies. However, in general, a 3.5 inch penis falls on the smaller side of average when erect, which typically ranges from 4 to 6 inches. It is important to remember that penis size is not necessarily an indication of sexual pleasure or performance, and many other factors such as communication, technique, and emotional connection can play a role in sexual satisfaction. If you have concerns or questions about your body or sex life, it is recommended to talk to a medical professional or a licensed therapist.
