I do think a lot of the people here are guilty of the same thing. Assuming if a person doesn't want to give up a picture immediately that they've got something to hide. It would be one thing if I had asked for a pic and then wouldn't give mine. There are a couple of reasons besides safety that I didn't want to display my pic.
I'm gorgeous
and I don't want the attention of guys who just want to have a good looking woman on their arm and aren't so concerned about substance...Okay, so maybe I'm exaggerating a little bit “not bad” is probably closer to the truth.
Actually, I knew a gal who tried EH and did not put up her profile picture. She, too, is absolutely drop-dead gorgeous. She just wanted a man to get to know her for herself first, which I understand. Although it did not help her connect with her EH matches.
In the real world, however, it's our face that first greets a person, not our personality (unfortunately).
