If you approach VS with an open mind and think of it strictly as a bit of fun, rather than building yourself up with the expectation that you will get what you see, it is worth trying 1 or 2 of these ads just to see what you get. Sometimes the minger that you meet is gagging for a good fuck and you get the ride of your life....... Sometimes!!!!
Better that than the dreamt of "instagram model" type with a "holier than thou" attitude.
