You mentioned that at 19, your penis appears very small when not erect, but reaches about 6 inches when erect—and this is making you feel scared or ashamed.
What you’re describing is actually normal for many men. Some have more visible length when flaccid, others grow more when erect—this is called a "grower," not a "shower." A 6-inch erection is within the healthy average range, and it doesn’t usually point to a problem with blood flow or
testosterone.
👉 Still, if you're feeling anxious or want to be sure everything is normal, consult me directly so I can guide you properly and clear your doubts:
