I had a guy a few weeks ago who arrived and then said "just checking, it's bareback right?"
I was like HAHA NO BRO
He said "Oh, well never mind"
I said Never mind anything, off you go mate
He was like "oh I drove so far to see you" I said I don't give a shit, I won't see anyone who obviously has regular unprotected sex, do one.
But I guess that's kind of the opposite of the OP's post!
I've only had a look and walk twice in 2 years, if you are confident your photos are accurate and you're not misleading anyone with your adverts then don't sweat it. Sometimes guys just lose their bottle and run away, making any excuse. There are also some twats who get off on turning up then walking away and have a wank over it later.
