How can you sending her a photo which she will delete help her security checks. It is only any good if she keeps the photo so if you attack her she can hand it to the police and say that is him. We don't need photos before meeting as there would be no discretion in that would there. All we would end up with is a laptop full of mens photos. However a great idea if she is planning to blackmail you as she has your photo you sent her to show the wife as proof you were having sex with her.
Never send a photo just as you would never give out any details. Its common sense
Obviously you wouldnt know IF she had deleted it so it relies on her word she would which might or might not be true, but as i dont just blindly believe the word of a complete stranger i wouldnt believe her so no photo from me, quite apart from punting not being dating so what i look like is irrelevant.
I would be thinking blackmail purposes if i got asked for a photo, i am not that stupid, i hope other punters arent either. No WG needs a photo of a punter, its not how punting has worked in the over 30 years i have been punting. Its like paying deposits, never in this lifetime would i do that either, again i am not that stupid.
