Attraction?
Love is something that science like a few things cannot measure and attraction or chemistry cannot be predicted or tested, because it is something that God has give us humans to overcome those funny ideas that some have in eugenics?
We have the real natural selection in a crowded two can meet across the body of humans with a look! it is one of the most truly amazing part of the human psyche that each of us meets our match and so the gene pool spreads out in varied combinations of mixtures and makes us unique from probably all other living things?
God said multiply and we are today with over eight billion on this planet! Marriage and relationships is not for everyone, but love is and loving does not have to be connected to sex! We can love the lost, the orphans, those suffering, our pets, our relatives within the confines of Gods rules!
