My standard for selection are at least one photo showing decent cleavage (at least a c-cup). I get suspicious is the only show images of her butt. I love long hair and prefer dark hair, but am ok with any colour hair. I prefer ladies between 5 foot 4 and 5 foot 8, but am not too strict on that.
A while back I was attracted to a friend and especially her hair and had fantasized about being enveloped in her hair, but didn't want to get into the complications of an affair, so I choose a lady based entirely on her hair.
Another time I choose a lady specifically for her name and because she looked very different from someone I wanted to forget about... I called it a name-ectomy. It worked... the name no longer affects me.
I love spy stories and part of the allure of my current favorite lady, was that her name had been used on a spy movie, and TV shows based on the movie.
I repeat with ladies who let me play with their hair, that I have fun with and interesting conversations.
