The Short Answer

Most animals have evolved this behavior so that their young one's growth coincides with the seasonal availability of food/resources. This also creates a cycle of birth and deaths that overlap so that the young can grow. This seasonal cycle is what we call being in heat. Humans don't have to because we are smart and make use of what we can to survive. So sex is more recreational than utilitarian.
