Many of our students feel that their lack of sexual fulfillment is due, in some part at least, to their husbands penis being inadequately sized.  Below you will find several graphs containing information that we have compiled from studies taken around the world and mixed with information compiled from our students.  Each of the graphs is a reflection of the world population of males who have been measured.  As a general rule there are no regional, racial or cultural differences in penis sizes.  The penis is simply a bodily tissue that, when aroused, fills with blood to become erect.  The penis is also constructed with a muscle that runs the length of the ventral (bottom) portion of the penis.  This muscle regulates the flow of urine and is also integral in maintaining erection as well as impeding or postponing the male orgasm by constricting or flexing.  Unlike other muscles that can be built up indefinitely the penis has a maximum growth potential.  In most cases that maximum size region is 200 to 250 mm.  If a penis is already at that size it can not be developed beyond 250 mm.  Penis size is also not reflective of any other size of the male anatomy, large feet or nose or fingers do not guarantee a large penis. 

In addition to the graphs below you will find two pictures pointing out the ventral muscle of the penis.  Each of these men are husbands of graduates of The Monticello Institute.  Each of these men has also had at least a 62% increase in the size of their penis as a direct side effect of their participation with their wives in The Monticello Institute.  These increases were caused by non surgical system.  They also never knew what their wives were doing, but they are pleased as are their wives with all of their physical changes.
Demographic information by age
The age groups of the students participating with The Monticello Institute are as follows.  The majority of our students are in the 35 to 44 age group.  The membership reflects how women generally feel their sex drives falling, however the 45+ group is lower than the preceding group not due to a resurgence in sex drive but feeling comfortable with a low sex drive and a feeling of normalcy with an unhappy marriage.


Demographic information by ethnicity
Our members are usually from educated households and are interested in improving their sexual relationships with their husbands and are aware that sex is not a duty but an expression of love.  This educated background as well as a good deal of self empowerment provide for our high percentage of white memberships.  Other ethnic groups have the same problems with their sex drives but do not usually have the information, education or cultural background to change what they feel could be changed for the better.  Part of this is that white women feel greater partnership in their marriages and less subservient to their husbands.


Penis comparative statistics
Circumcision
This is a compilation of studies from around the world about whether men have had their penises circumcised.  Due to the international nature of this study you may notice a large number of uncircumcised men.  If the study is confined to North America however a larger percentage of men are circumcised.


Widest point of erect penis
This list represents significant differences in the width or circumference of the males erect penis.


Penis circumference
This graph shows the general distribution of the circumference (how big around) of the male penis in millimeters (mm).  The measurement is an average of three measurements taken at the head of the penis, mid shaft and at the base.  As a good rule of thumb, the longer the penis the greater the circumference.  This increase in circumference is needed to support the greater length.


Penis length
This graph shows the general distribution of the circumference of the male penis in millimeters (mm).  The measurement is an average of three measurements taken at the head of the penis, mid shaft and at the base.  As a good rule of thumb, the longer the penis the greater the circumference.  This increase in circumference is needed to support the greater length.  For conversion calculations 1 inch = 25.4 mm.


Penis testimonials
Remember each of our students tells us what they find wrong in their relationships.  We help each of them through each of their issues.  Below are photos of the husbands of average students who were not happy with the sizes of their husbands penises.  We incorporated into their treatment ways to increase the length of their husband's penis.  We have never failed to change help any of our students in this matter.

This first picture is of one of our student graduates husband flexing his penis and his abdominal muscles.  As you can plainly see the ventral muscle is clearly pronounced on the surface of his penis.  The line also points to the approximate tip of his penis prior to his wife changing their lifestyle and his penis.  Our student tells us she is very satisfied with her husbands penis at approximately 225 mm.

This picture also demonstrates a pronounced ventral muscle on one of our graduates husband.  The line also points to his original length prior to his wife's joining The Monticello Institute.  This picture is also a little misleading as he is doing sit-ups and making his penis look like it goes well beyond his navel.  Our student tells us she is more than happy with her husbands penis at approximately 220 mm.
