It seems apropos the interpretation of Genesis that some do, and of the many writings considered sacred and base of different "religious" dogmas, where sexuality or sexual act is considered to impure, sinful and contrary to the sacred.
This, clearly, is neither a healthy nor proper interpretation. Because if there is a God who create sexed creatures and laying the golden rule of do not copulate, but with "freedom" to choose (will), surely God would be a morbid and somewhat sick.
However, the practice of celibacy is a sexual practice but something different from the known, it has not to do with pleasure and / or reproduction but with transcendence.
This practice is not known among animals, because a natural reason, they are not as evolved and do not have a conscience as human beings. It is this consciousness which moves some to want to transcend the animal experiencing so, that possibility.
You can not embark on the challenge of becoming celibate from a moral view, believing that this will make you more holy or elevated than others who do not even care about do it, which is totally valid.
