Well Wanda, I had a distinct idea in my mind when it came to defining "stranger", i.e. someone you had never met before the "occasion", no overtures...raw, purely lust driven...but since I've read Lorelei's answer...... that would qualify too.....
any scenario I guess where there is a degree of mystery about your partner.......you put your interpretation on it and share.....and Hey, stop blushing.....a blusher at Pixie's.....C,maan!
