I was wondering if there are ways to predict how good a girl will be
in bed.  I heard once that there was a website where you can type in
characteristics (height, personality, hair, etc...) and it will
predict for you... but I can't find it.
Is there a way to predict sex drive?

In recognition of statistically soundness I shall refrain from giving
any numbers for the moment - but suggest that these things probably
lack predictive value.

I don't think things like height, personality, and hair have much
relationship to how good someone is in bed. What makes a person good
in bed has less to do with external factors, and more to do with how
that person feels about you and how you feel about the person.

I don't mean to imply that it's necessary to be in love with someone
in order to enjoy sex with him or her. But if a certain psychological
spark isn't there, you aren't likely to have as good a time. And that
spark is something that no computer program is going to predict.

Take Pinkfreud's advice.  She would know.

If there is such a website, I expect that it always gives a
"promising" response, probably couched in nice phrases relating to
some of the input.

Women sexual potential is 10 to 1!!! Try books like She Comes First;
Multiple Orgasmic Men and Couples; The Butterfly...; Getting it on;
Femalia, and so on. That woman by your side ... she is that hot!

Yeah, the website I remember hearing about was actually mentioned in
Playboy once, but I don't think it exists anymore.... I just remember
it joking that people were gonna start looking for short women with
long hair... supposedly they were the answer for being good in bed. 
Obviously, not scientific, and very speculative, but it just made me
curious about any studies that might have done like this...

Make that "short women with long red hair," and you've got an even
more accurate description (says the short woman with long red hair).

Uncle!  I'll concede.   But Blondes have more fun!  ;-)

Lets see...a woman of average height, slight of build, pert, perky,
Irish, freckles, super smart, thick short brown hair, a smile that
lights up a room, practical disposition, great sense of humor (but
you'd never know it)....

Pinky, 
Are you bragging or something?  :-)  I note a slight contradiction in
your two postings, but Masters and Johnson discovered that experienced
strangers could do it quite well, so maybe technique is what counts.

>> Are you bragging or something?

Of those two choices, I guess the answer is "something." I was just
joking around. I really have no idea whether I am good in bed or not.
All I know is that no one has yet filed a formal complaint. ;-)
