Sex is nothing special especially at least to the human species of primates. If other animals are a good example (and they are) humans should be getting on with just about anything that moves or maybe even doesn't move warm or cold. You see it has been observed that the more intelligent an animal species is the more likely that animal species will mate just for fun and without much in the form of being selective, too young to breed, too old to breed, same sex, different animal species it doesn't matter.

Seems many humans are too tied up in old religions ideology of sexual purity.

Too bad, we can't go back to the times of sex temples where there were all kinds of sex such as bestiality, homosexuality, and quite possibly a lot more.
