There was a short crazy period in my youth when a whole bunch of girls were fighting over me. The reason they all wanted me was very simple:

Because the other girls wanted me!

Women are herd animals, and if something is hot in demand they think it has to be very valuable, so they want it too!

If you somehow manage to get a critical level of female attraction going, it just snowballs out of control all by itself, as every girl within 20 miles want in on the action.

In the end I picked the girl that wanted me first, before the others became interested. It turned out to be a smart choice, since she was one of the rare girls who makes up her own mind about things and don't just mindlessly follow the herd.

I'd recommend finding one of those, if you can.
