Various studies show only 5-10% of men have a penis over 7in in length and this falls to less than 1% for men over 8in in length, while when it comes to girth only 7.5% percent of men have a penis of circumference 5.5in or greater and this falls to 0.5% for men with circumference 6in or greater.
The studies of average erect penis length conducted on adult men worldwide included France 16 cm, Italy 16 cm, Mexico 15.9 cm, Germany 14.48 cm, Japan 13.0 cm, United States 12.9 cm, Saudi Arabia 12.4 cm, Brazil 12.4 cm, Greece 12.18 cm, India 10.2 cm and South Korea 9.6 cm. Three major scientific surveys (across all races) where researchers measured the length or male erections themselves suggested that the average length of a male erection was 5.08in (12.9cm), 5.35in (13.6cm) and 5.9in (14.9cm) respectively, so overall a rough average of 5.5in. Erect circumference average is 5in +/- 0.5in.
Ok so you are 4 inches and you may not quite fall into the average range but it'll be what you do with it that counts and trust me for most women girth counts for a whole lot more than length so as long as you have some girth and the will the pleasure a woman rather than be a lazy lover you should be fine
A good journal article to read on the subject can be found here:
