A very good question.Are we supposed to be monogamous or not? Further questons arise. Are you asking in a procreation way? Should we mate with several others so the species can flourish?To this,I would say no.The better idea would be to have one mate for life.Ah,but what influences the question is SEX as pleasure.Being a permissive kind of guy,I would say,why not enjoy this pleasure with as many or as few as you choose.It seems to me that socieity's concern is with the recreational or pleasurable side of how we choose to live our sex lives.Of course it is nobody's business with whom we choose to fuck.
