E-mail can reveal history or IP or other things, best left unknown until people feel comfortable with doxing themselves. PMs here are secure, and in my opinion, the best way to get to know someone before divulging personal information to. In fact, there is no urgency to giving an e-mail address.
I don't really know how to post a picture of my ear. Give me your phone # and I'll text you one. You can then post it for me if you want.
