Mmm, I would definitely keep them, but boxing them away sounds like the best option. I've always done this anyway, as I've never seen myself in those photographs.
I too realise that those few photos I do have of myself are (and will be) of my past, though I don't have many of these as I'm always behind the lens. Most photos of me are actually dotted around the family home. I can't very well ask my parents to take those down, and it would be strange to have this photographic paper trail which ends all of a sudden in my own photo albums. Instead I guess I've just become numb to these. I've developed an odd mental block around my own masculine self-image, which helps sanitise those memories somewhat - mental Photoshop. ^_^
