If sex were painful, creatures would be less likely to do it. By it being pleasurable, creatures are more likely to do it.
Since caretaking can in some environments increase survival rates of offspring, one would expect the evolution of altruism in these situations.

The more diverse a population is, the faster evolution can take place. When a species procreates through single sex reproduction, it is less diverse. So the first organism to use two individuals to reproduce would instantly be more beneficial. That happened vary early and led to two sexes.
Sex and procreation was very quickly made into an instinct to desire and enjoy sex. Think about it, if you had two species, one enjoyed sex and the other was indifferent, which one would procreate more? The one that procreates more will also have a better chance at survival because its population would increase faster.
Being a social animal is also a positive adaptation for reasons too complex to get into here. So feelings of love, families, tribes, and sexual partners developed as a way to maintain and use those positive attributes associated with being a social species.
Evolution, or more accurately, Anthropology answers your questions with amazing amount of scientific info and understanding.

"If that was the case then we would of evolved into procreating only like cells can in a pitri dish..."
Where did you read this?Sexual reproduction allows a greater genetic diversity,allowing for a greater chance of survival. WHO taught you as fact that evolution says we should procreate like cells in a petrie dish?be honest. Your pastor?
Then you said"How would evolution explain why sex would evolve into a pleasurable experience, so that every species would continue to partake in the activity, for as long as earth is here?" Here you answered your own question. It evolved so it would be pleasurable.Now,if it WASN'T pleasurable,that wouldn't exactly be a beneficial advantage towards reproduction would it?So your second point actually gives more weight to evolutionary theory,rather than discredit it.
Finally you said"How would evolution explain that the attraction male and females would have for one another would transpire into feelings of Love, Sex and creating families or tribes?Man is a social animal,and we are NOT the only animal that can feel love,pain,or remorse. There are primates that show remorse when their partner/child dies. But love also helps in continuity of the species. If one has strong feelings to their partner,it would be beneficial towards the passing on of their genes. On the females part,love would insure that it is indeed the particular mans offspring she is carrying. And for males,an incentive to assist the pregnant female

First, understand that you can have sexual reproduction without 2 dedicated sexes. Most flowering plants, for example, still use the system of sexual reproduction where all individuals are both males and females. Dedicated sexes is just one of many variations on sexual reproduction.
So the question is not about manifesting 2 sexes, but about the invention of sexual reproduction. There are *many* books on this topic (I suggest you read at least one of them before concluding that evolution has no way of explaining sexual reproduction).
> "How would evolution explain why sex would evolve into a pleasurable experience"
Uhm ... this is kinda easy. Anything that makes an organism want to reproduce more, is good for that species.
> "How would evolution explain that the attraction male and females would have for one another would transpire into feelings of Love, Sex and creating families or tribes?"
Because all of these things, these emotions, have obvious evolutionary advantages. What we call "love" probably transcends biology. But its roots are in biology. Whether you call the feeling that two emperor penguins have for each other "love" is up to you. But it certainly has advantages for the penguin species (it turns penguin couples into a cooperating team ensuring the survival of the egg).
> "GOD answers each one of these questions, if you are telling me Evolution does than here's your chance...:)"
Evolution has answers for some of these questions ... but some of these questions go beyond what Evolution claims to explain.
For example, when you use a word like "love", you are invoking a spiritual meaning. This is fine (I have a similar definition for "love"), but that puts it in the same category as words like "God" or "soul" ... questions that Evolution does not claim to answer.
But sex? Yes. Evolution explains it (it provides the advantages of increased variation, which is the raw material for natural selection).
And pleasurable sex? Yes. Evolution explains it (it induces animals to reproduce, which is also necessary for evolution).
And creating families and tribes? Yes. Evolution explains that too (social cooperation increases the chances for success and survival).
And none of these explanations contradicts the GOD explanation. *That* is the concept I think you are missing. Both explanations can both be true! Neither one excludes the other. Stop pitting science against religion ... this is a FALSE choice! And a *tragic* one if you choose one to the exclusion of the other.

Genetic bio-diversity. An exact copy of the original is all we would get if we only had asexual reproduction. As a result, flaws in higher organisms would end in the death of species since a copy of a copy is never as good as the original. By mixing and matching we ensure that a single disease that one race is vulnerable to and another has resistance to doesn't wipe out the species. This is the very reason incest is a bad idea. Flaws in one family genome only heighten with each generation. By diluting it with another family line, the flaws are mitigated. Simple high school biology genetics here, nothing fancy. Sex is pleasurable because animals tend to avoid that which isn't and the species would die as a result.

Child, read a science book. You're too young to be on here. And you obviously don't know what you're talking about.
Evolution created different SPECIES to adapt to their environments. You're not paying attention.
Sex is pleasurable so that people will continue to do it and continue their species.
Attraction and love create more stable family units to protect the children and give them a better chance of surviving.

There's no need for the petri dish. Bacteria are reproducing asexually in your intestines as we speak. Somewhere, a female lizard is laying eggs that are female clones of herself, since evolution took a turn and her species has no males. You failed to explain these facts.
Pleasure drive creatures to reproduce. Survival trait. Pleasure only exists in higher animals with reasonably complex brains with pleasure centers. Even higher reasoning powers let the pleasurable feeling become more abstract.

Erm,
Mixing genes leads to more diversity and greater chances of surviving, thriving and reproducing.
Creatures that enjoy sex have this tendency to do it more frequently. Which again leads to greater chances of reproducing.
Bonding between mates or family groups significantly increases the chances that offspring will survive, thrive and live long enough to reproduce.
Evolutionary theory has all of these well covered. Maybe you should study up before you ask.

The only reason why sex is pleasurable is because of the intensity of nerve endings located at our genitals. By the way, the only organisms known to have recreational sex are Humans, Dolphins, and Bonobo apes.

Why have many species of male bird developed beautiful plumages?
To attract females.The basic instinct to procreate is within all species on the planet.We humans have chosen to refer to it as attraction
