Long fingernails
I was about 5 years old when I got 'imprinted' (yup, that's the clinical term). I was watching the 3 Stooges (for our British viewers the 3 Stooges were the absolute lowest common denominator of slapstick humor; sorry humour). The Stooges were captured by 3 amazons who announced they were going to, "love them to death." And, wait for it, when the amazons turned around they were wearing long, extraordinarily fake fingernails. This was the most amazing, erotic thing I had ever seen in all of my five years on this planet and I immediately popped the first woody of my life.

That was it. Ever since I have been aroused by long fingernails (though in later years even shorter but well-manicured nails will do). Mrs. Mad Scientist keeps her nails longish and painted blood red and I couldn't be happier (so remember kids, always tell your significant other about any fetishes you may have so that your relationships have half a chance of working).

Thanks to the interwebs I've discovered that I'm not alone. There's at least 35,000 of us 'nail fetishists' out there. And we all seem to have been imprinted at an early age. Indeed, my research on the subject seems to indicate that the stronger the libido the earlier the imprinting (of whatever your fetish).

Imprinting...
Well, it's not like we have a choice with what we get imprinted. I'm just grateful it wasn't something off-putting (as my British friends say) like a club foot, bad teeth or whatever.

Nail fashions have been pretty interesting over the decades. I rather enjoyed the dark goth trend and the French manicures before them. Currently long nails aren't 'in'. Hopefully that will change in another decade.
