There was a very funny discussion some years ago titled something like 'Jehovah's useless penis', It was deleted and reinstated at least once and appears to be permanently gone, which is a shame because it highlighted the extreme lengths some people will go to, to massage sense from the ridiculous. Maybe my search skills aren't what they used to be and it is still here but I just can't find it?
God made man in his image, so Adam didn't have a penis and there would have been no childbirth pain because Eve wasn't made with human kind's current female bits, etc....
