Promiscuity.

So as most of my readers know, I am now part of a blogging network.  I've discovered quite a few interesting, hilarious, insightful blogs out there - one of them being Hooking Up Smart.

A couple of this blog's recent posts have stirred some thoughts in my mind.  There's a point brought up that men who've, ahem, been around the block, are not the best husband material (don't buy the floor model, ladies!).  Also, there's another post in which the potential economic consequences of promiscuity are outlined.

This lead me to a question.   Let's say, for argument sake, one is completely careful in protecting oneself and others from unwanted pregnancy and any disease (which I know is a bit of a big leap at times) - are there other potential negative consequences of casual hookups?   Are there other unforseen problems with promiscuity?  Or, can it, in the right context, if everyone is on the same page, be harmless?

I know the church and various elders/traditionalists have their views on this.  I have, on many occasions, heard various people insist that there would be no harm to a casual encounter.  Are there other consequences to individuals (or society on the whole) that are not immediately seen by the blind eye?  Or, is there a safe place for some casual, ahem, encounters?   Do some people, at times, see them as necessary?  Your thoughts?  Your own experiences?

Please share.
