If there are 8 million people in London and only about 4 million are males.
Then we take males that want nothing to do with females, leaves around 3.5 millions.
While most of the population is young that takes away about a million individuals below 25 yrs old. and takes away another million which are over 35 yr old. There are 1.5 million males left, but let say 70% are married because of the age ... whcih most are marry as early as 20 in many statistics. You are left with 800-900K males. now half of them are less than 6 inches. so you have 400k males now. of those 6-9 inches are actually almost 99 % so there are 4000 males that you could have in London alone that are single and have more than 9 inches. But heck you want 9.5+ that becomes even harder of those 9 inchers and up only 25% are 9.5+ inches. So you have only 1000 to shose from. Of those 1000's since they are 25-35 years old and big dicks you must believe for sure that t least 40% will have ED so you are left with 600. Even though a few of them may have STD's that would take away a few of them.But of those 500's that are in London which is a big city it would be hard to find them
the funny thing is more than half of them will fail the required 6+ inches of girth...
Now with less than 300 left in the whole city you need to find out how many of them dont have a girlfriend they love and wish to marry!
