"Attraction isn't a Choice" by David D. Angelo ... lolo
You have nano-seconds to decide if you talk that person in the first place or not. Why, yes, of course, it's their wonderful personality, great bantering skills, their people'ness, their shared interest ... come on girls wake up!
Topic is physical attraction

So, I say +1 being important. However, strongly agree that after the urge many more things become even more important.
And agree, that if you're not satisfied at home, you will wander.
"never leave the dog out at night"
Unless, ... viagra doesn't help. for the pure injection side of thigns.
hugs, kisses, touch of skin, are important ... I especially enjoy the finer side of our species.
I also think that "fit" is important. Physically speaking. Also, on the mental side if your other has some "kinks" then those should "fit" too to some degree. If not, you will be found wanting.
We as animals are given certain instruments to propogate are species and fortunately they are not only limited to only
mating purposes. I think that we are the only species that actively "mate" for non-mating reasons.
