From this little article:
"If you want to find a lover, limit your choices. It turns out that the more options you have for choosing a lover, the more likely it is you will end up all alone."
"The takeaway: People are more likely to choose no one at all when faced with greater variety."
So *my* takeaway is limit your choices to those who seem as though they would be interested in karezza! Yes, the pool gets smaller, but it's so much more fun to swim in!!
