i would imagine that after a certain point our brains developed to the lvl where we did do it for fun, and any previous signals to indicate ovulation was no longer needed and faded with time.

Women are more open during those days and such and gamer is right. The way the ladies dress is also diffrent(so i have observed)

There's so much philosophical reading on this I won't even start. Get reading!

this is a silly topic.  First of all, it's assuming we are like all other creatures on this planet, which clearly we are not.  Secondly, it is fun. 

we aren't critters

"I just think Justinian I needs to get laid a bit before he should worry about this subject matter. A little experience will give him a lot of perspective."

A steady realationship will teach you much more about how to guess the ovulation cycle than just getting laid with everyone. You need to know a person habits in order to detect the difference. And you can even use it to your advantage.

OP:

Is this an attack on Natural Law arguments against non-reproductive sex? If so, I agree There are loads of natural indicators that humans are designed to enjoy sex as well as have babies.

But you must remember that the female menstrual cycle is very random, except for the period of actual bleeding; at ANY other time of the month there's a possibiltity a woman's ovulating. It varies from woman to woman, and even a woman's personal 'fertile' period in her cycle fluctuates. It's not like there's any one dead-certain time per month where a woman will not be fertile. So, it makes sense that she gives out 'hump me' signs at all non-menstruating times, because there's the chance she's ovluating at any of those times, quite unlike other species. Human females ARE the most fertile of all female mammals

Btw, unless you get some die-hard evangelists und so weiter in here, there are't really going to be any arguments about sex for enjoyment :S

Oh, don't get personal >:[ like you get so much reprodutcion done

There is no consensus yet on the ability of a male human to determine a female's fertility.

However, many of the posters in this thread have nearly hit the nail on the head. Humans are social butterflies, our community is extremely important to our survival. Without the intercooperation of other members within our species, the hunter/gatherer society would have been impossible and by extension, all of modern civilization would have been impossible. United, humans are that much more productive than if they had to fend for themselves in isolation. Having said that, the importance of creating emotional bonds with others in our species has only been emphasized by the concealed ovulation of human females. The more we get to know the other, the better we can judge their menstrual cycles. Consequently, human sexuality has become more than just a method of producing offspring, it also serves a social function. It, too, could be a method of establishing strong bonds with other members in the species. The hidden estrus of human females also gives incentive for the long-term relationship, which would benefit offspring by the introduction of the two-parent family.

you could still have sex with a woman canadia.

> Justinian I wrote:

> In most every other species the female has telling signs that she is ovulating, and only during this time will she copulate and do it to reproduce. But in humans, the best we can do to predict whether a female is ovulating without scientific equipment is to have knowledge of a woman's menstrual cycle. Otherwise, at any given moment we do not know if a female is ovulating or not, and yet at the same time we copulate even when she is not ovulating.

It kind of suggests that while every other critter is copulating to reproduce, we are doing it for fun.

Seriously, wtf?<

Humans are NOT the only animals to have sex for pleasure, Dolphins do it all the time.

dolphins love sex, and form male pair bonds, perhaps showing that homosexuality isnt purely social?  bonobo monkeys love sex too, do it as many times a day as possible, if they have a confrontation, BAM, instantly taken care of with a quick hump.  Think im kidding?  Look them up, fascinating.
