There is no shortage of Sociological, Psychological Religious and Political naysayers trying to justify conformity to current norms. If we listened to them without challenge, little societal change would ever take place. Women would remain second class citizens, racial inequality would be justified, etc There is no absolute correct answer, however if we observe our primate ancestors it is clear that most are NOT monogamous, and open playful sexuality is the norm. We don't own other humans, and neither should we constrain sexual play as a means to reinforce common bonding within and between the sexes.
Lots of "well accepted" science is debunked daily. Rid's attempt to reinforce his religious / socialized outlook demonstrates a very constrained personality, certainly not shared by many who have joyfully embraced their sexuality as members of this EROTIC REVIEW BOARD !
