Hi Outback...interesting question.  I know I myself am intrigued by an "almost can see it" shot...It creates a bit of suspense...gets your mind thinking as to what is there and available .  Sometimes these type of photos create a conversation that can go in many directions. Builds up the suspense for the actual possible meeting.  Now don't get me wrong...an all out pic is nice too...Don't think many would disagree with that.  I guess I like to leave a little to the imagination (guess my photos don't completely do that...lol).  I think everyone has a little different twist on what makes them excited/interested and want to persue a profile...but pics of any sort certainly help that along...even a "g rated" pic can arouse an interest for more.  Not everything is about xrated pics.
