Sounds like a story that happened to a straight mate of mine. He had a relationship, but his girlfriend started having problems which were taking longer and longer to heal. And the reason was that he was too big. I dont quite understand why it worked in the beginning, but she apparently apparently always had some issues and infections to the point that their sex was a frustrating affair: he was afrait of hurting her, she was afraid of facing issues again, until their relationship fell apart. Obviously this wasn the only reason (I gather), but he told me over and over again he wished he had an average size dick and would do it if it made them come back together... So I dont think your girl was making this up. She might have had past experience...
