I met my girlfriend online. We spoke online for about 2 years or so before finally meeting.
She had sent me photos, and I had sent her photos. Before I left to the UK to meet her, we spent 3 or 4 months talking on cam every day over skype and msn.
However, when we met up she did not look quite like she looked in photos and cam. She did not send fake photos, or use filters or anything like that, it was just her on cam. I think it has something to do with the brain, making a transition from 2D to 3D.
She told me I did not look the same as I did on cam or in photos too, and I know I did not do anything to alter my photos or cam feed either. So I am quite sure, there is something going on in the mind. You get so much more detail in real life.
No unpleasant surprises though, she looked even better in person than on cam.
