There are over 6 billion people on the planet. Just find someone else
Assuming there is equal distrobution of people, with ~57,500,000 square miles of land and 6,000,000,000 people, that makes out for approximately 105 people in a square mile.
Now let's take that one step further and apply the ten-percent of people are gay factor, and you have about 15 people per square mile who are gay.
Of course, being gay means that you only want the males, so split that in half. In the end you get an average of less than 8 people per square mile who are gay.
Oh, we should also take age ranges into consideration. We most likely aren't going to want anyone over 64, and definitely no one under 18. We can figure probably two-thirds of our remaining number is still within our critera. That leaves our average at about 5 people per square mile.
Of course, there aren't an equal distrobution of people. There will be more people per square mile in large cities and even less per square mile in small towns and in the country.
Memphis, Tennessee has 2327.4 people per square mile. That means it has 110 gay males in the range of 18 to 64 per square mile. There are 279.3 square miles of land in the city so that means there are 30,723 people in Memphis, Tennessee.
Dyersburg, Tennessee has 1,158.7 people per square mile. That means it has 55 gay males in the range of 18 to 64 per square mile. There are only 15.1 square miles of land in the town so that means there are only 825 people in Dyersburg, TN.
Somewhere into that equation needs to be factored personalities, "friend circles," availability, religious oppression, and simply being closeted.
I'd say the odds are pretty bad of "just find someone else", especially if you don't live in or somewhere relatively close to a large city.
