Question: is 5 inches a good girth size?
Answer: It's the question we've all been pondering over for years...just what is the perfect penis girth to length ratio? ... In fact, the "ideal" penis is 7.25-8.25 inches long and 6.25-6.5 inches in circumference. Deemed as unsatisfying is a penis less than 5 inches long, or with a girth under 4.5 inches or over 7.5 inches.
