Well, Pete,
As it happened just last weekend, in fact, I was sent a kind reply message to my initial hello message andasked whether I "have a big dick" as - according to the 'lady's' own testimony she needed a "minimum of 17 cm to satisfy" her.
I guess that sending a photo in this case would have either spared her any further question or made her look forward to a special treat - I leave that one up to speculation ...
