I had crushes on my teachers and other older women growing up; I think it is part of becoming a woman and looking for role models, mentoring figures, etc. If you don't feel anything "sexual" toward them, just want to be "with" them or talk to them or wish they'd notice you, etc. I think that's a typical wanting help with the difficult part of maturing. I still wish I knew an older, "wiser" woman :-) who could advise me and that would make me feel I'm okay and doing things "right".
