They just use them for free sex basically. Hump and dump is the motto.

Only way to get a new one every other week (day?) I guess?

You can't also just call on a tuesday night a 3-5% woman and expect her to be on your doorsteps in 1 hour if you're feeling horney.

I don't think the real number is 3~5% though.

Because (and I say this with the utmost affection, because not only are most of my friends men, but I am too) men not worried about long-term relationships are absolute sluts. And most will admit to it too.
