Gosh, just caught up from the last thread! Can't believe it is no 49 already...
I think sending of cock pics, just like asking for naked pics of us (especially when you've never even met them) all down to a sense of entitlement. I suspect the cock pics senders (because they clearly want to see naked pics of women) think that by sending a photo of their often fairly undersized member we will a) be impressed/aroused and b) reciprocate with a naked shot ourselves. It's the 21st century version of I'll show you mine, you show me yours, but without asking first 
MsC I must apologise for not responding to your post on the last thread, I did intend to (you said something v kind about me and C which I agree with, and I meant to thank you for it). What you said about whitevan man is something I've found, men who seem keen to meet, then at the 11th hour ask for a naked photo or (as has also happened to me) try and get a guarantee of sex...a refusal to either or both tends to result in them flaking. Pathetic but true! what ever happened to the guy you rescued from the snow (I dont think that was mr CM was it?) did you ever see him again?
