Lactantius,
Ante-Nicene Fathers Vol. VII, The Divine Institutes…
(1885)
“ For since the multitude of men is incredible, and their number not to be estimated—though, as they are born, they must of necessity die—what must we suppose to be the case with the gods who have been born through so many ages, and have remained immortal? How is it, then, that so few are worshipped? Unless we think by any means that there are two sexes of the gods, not for the sake of generation, but for mere gratification, and that the gods practise those things which men are ashamed to do, and to submit to. ”
